d-alex / ropencv Goto Github PK

I noticed that when I was in rails console (or irb) and did an imread on a medium sized photos, the CPU would just spinning. This is happening because matrices are displayed in the matlab format (which I love). Good for small matrices, bad for big ones. Perhaps just display the object when the matrix is of a certain size.

In the meantime, there is an easy work around by suffixing the command with nil:
img = cv::imread(my_path); nil

Can we have an example of how to use HogDescriptor in ropencv, as it seems in opencv
hog.setSVMDetector takes HOGDescriptor::getDefaultPeopleDetector() as an argument

while in ropencv the wrappers for HOGDescriptor::getDefaultPeopleDetector() returns Std::Vector::Float while hog.setSVMDetector expects Cv::Mat

Hi! This is a very cool project. I'm having trouble getting started. I'm running into this error when I try to require 'ropencv'.

Any chance you will support estimateRigidTransform? I noticed that it exists in the clang branch? The last commit on that branch seems relatively old compared to the master? How stable is it?

BackgroundSubtractor class and all its methods are missing in the docs, any help on how to use it will be appreciated

Instantiating a new FlannBasedMatcher:

require 'ropencv'
include OpenCV

matcher = cv::FlannBasedMatcher.new

the following error occurs:

NameError: undefined local variable or method `flann' for OpenCV::Cv::FlannBasedMatcher:Class
from /home/paolo/.rvm/gems/ruby-2.0.0-p598/gems/ropencv-0.0.21/lib/ropencv/ropencv_types.rb:32672:in `new'

So the error is on the following line:

# overloaded method wrapper for cv::FlannBasedMatcher::FlannBasedMatcher(const cv::Ptr<cv::flann::IndexParams> indexParams = makePtr<flann::KDTreeIndexParams>(), const cv::Ptr<cv::flann::SearchParams> searchParams = makePtr<flann::SearchParams>())
@@cv_flann_based_matcher_flann_based_matcher_defaults0 ||= [cv::Ptr<flann::KDTreeIndexParams>(new flann::KDTreeIndexParams), cv::Ptr<flann::SearchParams>(new flann::SearchParams)]

It seems to me that the flann namespace does not exists or it is not correctly wrapped/exported. In fact I cannot find other references neither to flann nor to KDTreeIndexParams in the file.

Can you please check and tell me if I am missing anything?

Ruby 3.2 removes the previously deprecated Kernel#=~ method.

With this method removed this line throws NoMethodError:

Hi, I have compiled opencv-3.1.0 enabling the opencv_contrib module so that I can use SIFT and SURF, for example using the Python wrapper with the official tutorials.

Is it possible to use them with ropencv too?

I am tryng to build ropencv on heroku, first using the apt buildpack to install libopencv-dev, g++ and cmake, then installing ropencv with the standard buildpck.

Any ideas? ruby-opencv wil install without problems.

Referring to the code below grab() or retrieve() never return false on reaching the end of file , instead restart reading the file causing an infinite loop

video_file = cv::VideoCapture.new(video_path)

while video_file.grab
frame = cv::Mat.new
output = video_file.retrieve(frame)
break unless output
frame_name = Time.now.strftime('frame_%Y%m%d%H%M%S%L.jpg')
cv::imwrite(File.join(output_path,frame_name),frame)
end

I'm getting this error in ropencv_ruby.rb line 326. Here is an exert from the from the code (within the Mat class):

def self.to_native(obj,context)
    if obj.is_a?(Std::Vector::Cv_Point)
        cv::Mat.new(obj.size,1,cv::CV_32SC2,obj.data,cv::Mat::AUTO_STEP).__obj_ptr__
    elsif obj.is_a?(Std::Vector::Cv_Point2f)
        cv::Mat.new(obj.size,1,cv::CV_32FC2,obj.data,cv::Mat::AUTO_STEP).__obj_ptr__
    elsif obj.is_a?(Std::Vector::Cv_Point3f)
        cv::Mat.new(obj.size,1,cv::CV_32FC3,obj.data,cv::Mat::AUTO_STEP).__obj_ptr__
    elsif obj.is_a?(Std::Vector::Fixnum)
        cv::Mat.new(obj.size,1,cv::CV_32SC1,obj.data,cv::Mat::AUTO_STEP).__obj_ptr__
...

The cv method is not defined in Mat. When I run my app specs, I don't see this issue, but when I run in development mode, I'm getting the error.

I'm doing my best to troubleshoot, but running into walls. From my understanding, the Mat class does not have access to the cv method defined in the grandparent module unless Mat includes the grandparent module, so the error seems reasonable.

As an example:

module A
  def a; :a; end
  class B
    def b; a; end
  end
end

A::B.new().b will fail unless B includes A.

Why this works in my specs is beyond me. Any ideas?

Would you be open to changing references to cv::Mat to self, or more explicitly, OpenCV::Cv::Mat in the above code. I can put together a pull request if you like.

Everything seems to install fine but when I try to load ropencv I keep getting the error below. Any help is appreciated.

Hi Alexander,

Any chance you'd bump the version coincide with the latest master?

When I try to bundle install ropencv via your repository I get the following message:

Using ropencv (0.0.12) from https://github.com/D-Alex/ropencv (at master) 
ropencv at /Users/cgat/.rvm/gems/ruby-1.9.3-p194/bundler/gems/ropencv-419e5f1a68e5 did not have a valid gemspec.
This prevents bundler from installing bins or native extensions, but that may not affect its functionality.
If you need to use this package without installing it from a gem repository, please contact ["[email protected]"] and ask them to modify their .gemspec so it can work with `gem build`.
The validation message from Rubygems was:
  ["lib/ropencv/ropencv_types.rb"] are not files

Otherwise I have to use a local fork that I've built manually.

Thanks

I'm trying to translate the last three lines in the snippet below from C++ to Ruby. Any help would be much appreciated. Thank you!

 cv::Mat image= cv::imread("boldt.jpg");

int i= rand()%image.cols;
int j= rand()%image.rows;

# Set the value to white
image.at<cv::Vec3b>(j,i)[0]= 255;
image.at<cv::Vec3b>(j,i)[1]= 255;
image.at<cv::Vec3b>(j,i)[2]= 255;

any help will be appreciated as openCV is installed without any errors

Suggestions welcome :)

I wasn't able to get ropencv working with nginx/passenger for some reason. It works fine with unicorn, webrick, or from irb on the same system, so perhaps it's a problem with passenger. Regardless, I thought I would post this here just in case anyone else experienced the same issue.

Configuration details:
Mac OSX 10.7.5
Passenger 4.0.37 (via hombrew)
Nginx 1.4.5

Seg fault occurred on the warp_affine function according the nginx log file.

Hi, this is a great tool for teaching. Thanks for that.

I am unable to find a way to access the gui trackbar, is there a function for that? If not, how can I implement it ?

When using the findContours function, the returned hierarchy is a row matrix with as many columns as contours.

Based on the documentation of OpenCV, the hierarchy should be n x 4 where n is the number of contours. I expected the type of the hierarchy to be Std::vector::Cv_Vec4i.

In the current situation, the hierarchy variable is useless.

I am having trouble installing the ropencv gem on OS X Yosemite 10.10.3, Ruby 2.1.4. Installed openCV 2.4.11 using Homebrew.

Getting this error - don't suppose you have any ideas at all?

What is the most efficient method for pixel by pixel processing/manipulation using ropencv? With the C++ interface this could be done use ptr function on Mat or an cv::Mat_<cv::Vec3b>::iterator. Thank you for you help.

not an issue, more a feature request

what would be the steps to install your bindings on a machine, that

• does not allow you to install anything the usual way ( you're not root, there's no apt-get or anything, and no, you're not allowed to install anything to /usr/lib, /usr/local or similar, so the gem install ropencv just won't work )
• you only got curl, git, and g++ at your hands (well , yikes, that means building even cmake from scratch..).

again, imho, you're doing great, take this more as an additional sportive challenge ;)

(and again, - while most of opencv requirements pretty much assume, you own the machine, ruby, being more a web-dev language might challenge that idea, no ?)

Several of the constructors for Mat are missing.

For example, an important prototype used for cropping images is Mat::Mat(const Mat& m, const Rect& roi), which yields the error:

[8] pry(main)> mat_crop = OpenCV::Cv::Mat.new(mat, rect)
ArgumentError: no constructor for OpenCV::Cv::Mat([#<OpenCV::Cv::Mat:0x007fd9a620edb0 @__obj_ptr__=#<OpenCV::Cv::MatStruct:0x007fd9a620e9a0>>, #<OpenCV::Cv::Rect:0x007fd9a613cdd8 @__obj_ptr__=#<OpenCV::Cv::RectStruct:0x007fd9a613ccc0>>])

Attempting to construct a Mat using the prototype Mat::Mat(const Mat& m, const Range& rowRange, const Range& colRange=Range::all() ) yields

[13] pry(main)> mat_crop = OpenCV::Cv::Mat.new(mat, row_range, col_range) 
ArgumentError: no constructor for OpenCV::Cv::Mat([#<OpenCV::Cv::Mat:0x007fd9a620edb0  @__obj_ptr__=#<OpenCV::Cv::MatStruct:0x007fd9a620e9a0>>, #<OpenCV::Cv::Range:0x007fd9a51eeae8 @__obj_ptr__=#<OpenCV::Cv::RangeStruct:0x007fd9a51ee098>>, #<OpenCV::Cv::Range:0x007fd9a4e2c298 @__obj_ptr__=#<OpenCV::Cv::RangeStruct:0x007fd9a4e276a8>>])

based on the documentation, i think that Circles is supposed to be a vector

circles – Output vector of found circles. Each vector is encoded as a 3-element floating-point vector (x, y, radius) .

fitting it to
cv.HoughCircles void
Mat image
Mat circles /O
int method
double dp
double minDist
double param1 100
double param2 100
int minRadius 0
int maxRadius 0

i get an error that the content doesn't type doesn't match or an error that the content is wrong.

circles.size if a ptr if you set it up as Mat,

of course i could just be confused as how to translate vector circles to ruby

my code

def test_hough
hough_circles 'public/g/edit_images/stuff.jpg'
end

def hough_circles(img_name)
#Mat src, src_gray

#/ Read the image
src = cv::imread(img_name, 1)

return -1 unless src.data
src_gray=src
#/ Convert it to gray
cv::cvtColor(src, src_gray, CV_BGR2GRAY)

#/ Reduce the noise so we avoid false circle detection
arraysize=cv::Size.new
arraysize.width=9
arraysize.height=9
cv::GaussianBlur(src_gray, src_gray, arraysize, 2, 2)

arraysize.width=3
arraysize.height=1
circles=cv::Mat.new(arraysize,cv::CV_64F)

#circles=Vector::Mat.new
#Vector(3,1,cv::CV_64F)

#/ Apply the Hough Transform to find the circles

cv::HoughCircles(src_gray, circles, CV_HOUGH_GRADIENT, 1, src_gray.rows/8, 200, 100, 0, 0)

#/ Draw the circles detected

(0..circles.size).each do |i|
Point center(cvRound(circles[i][0]), cvRound(circles[i][1]))
radius = cvRound(circles[i][2])
# circle center
circle(src, center, 3, Scalar(0, 255, 0), -1, 8, 0)
# circle outline
circle(src, center, radius, Scalar(0, 0, 255), 3, 8, 0)
end

#/ Show your results
namedWindow("Hough Circle Transform Demo", cv::CV_WINDOW_AUTOSIZE)
imshow("Hough Circle Transform Demo", src)

end

Hi,

congrats on the project, I am using ruby-opencv but wanted to give this gem a go.

I am loosing following this tutorial:
http://docs.opencv.org/doc/tutorials/objdetect/cascade_classifier/cascade_classifier.html#cascade-classifier

require 'ropencv'
include OpenCV
face_cascade_name = "haarcascade_frontalface_alt_tree.xml"
face_cascade = cv::CascadeClassifier
face_cascade.load(face_cascade_name)

and I am getting:
run.rb:5:in <main>': private methodload' called for OpenCV::Cv::CascadeClassifier:Class (NoMethodError)

When i try and use
matcher= cv::BFMatcher::create('NORM_L1')
i get an error, that NORM_L1 is unknown matcher type. Matches the CV documentation
http://docs.opencv.org/modules/features2d/doc/common_interfaces_of_descriptor_matchers.html#BFMatcher : public DescriptorMatcher

if I use cv::NORM_L1, it complains that it's an integer instead of a string, i'm lost, any help?

I'm struggling with cv::find_contours and it's quite likely that I do not know how to construct the expected input params. Help for a noob would be most appreciated.

I have:

thresh = cv::Mat.new
cv::threshold(gray_blue, thresh, 10, 255, cv::THRESH_BINARY)

...which makes a nice binary image for me from my gray_blue Mat and then:

contours = Vector.new(Vector.new(cv::Point))
hierarchy = cv::Vec4i.new
cv::find_contours(thresh, contours, hierarchy, cv::RETR_TREE, cv::CHAIN_APPROX_SIMPLE)

...but this fails with an ArgumentError. I'm assuming it's because of how I'm creating/passing contours or hierarchy. What's the correct way to make these to pass them into the findContours method?

I'm trying to figure out how to create GoodFeaturesToTrackDetector but be able to specify the parameters it takes.

Going off the C++ documentation:

GoodFeaturesToTrackDetector( const GoodFeaturesToTrackDetector::Params& params=
                                            GoodFeaturesToTrackDetector::Params() );
    GoodFeaturesToTrackDetector( int maxCorners, double qualityLevel,
                                 double minDistance, int blockSize=3,
                                 bool useHarrisDetector=false, double k=0.04 );

It would seem we can do this but I cannot figure out how rbopencv is binding this properly.

I've tried:

cv::GoodFeaturesToTrackDetector.new
cv::FeatureDetector::GoodFeaturesToTrackDetector.new

But no luck.

Thanks!

Thanks for fixing the gem installation.

I've now installed the gem and am getting the following errors when running the examples. Not sure what I'm doing wrong?

I've tried to run examples with 2.4.8, 2.4.10 and 3.0.0 (trunk), and match_keypoints.rb example didn't worked for those versions. 2.4.8 and 3.0.0 related to #26 and 2.4.10 isn't supported at all.

I'm running OS X mavericks. I'm installing from the latest source - although I had to modify the gem spec to remove the reference to ["lib/ropencv/ropencv_types.rb","lib/ropencv/ropencv_ruby.rb"] or it wouldn't build.

How do you access the shape off of an image?

image = OpenCV.cv.imread('/to/my/file.png')
puts image.shape

The above throws:

undefined method `shape' for #<OpenCV::Cv::Mat:0x007fc4f6c082e0>

On running the ruby find_keypoints.rb there are raisen an exception:

`method_missing': Ptr cv::Ptr is empty. Cannot call detect on it! (RuntimeError)

There is a problem installing gem in two cases: a) from rubygems and b) from GitHub source on OSX Maverick with Clang 5.0 and OpenCV 2.4.7

In a) case it says that opencv 2.4.7 is not supported. Looks like the gem is simply not updated, while master on GitHub solved it (updating \ext\helper.rb).

In b) case two things

1. 'lib\ropencv\ropencv_types.rb' is missing, while gemspec references to it
2. while installing it throws several errors of "expected ';' after top level declarator".

The moment is
Scanning dependencies of target rbind_opencv
[ 50%] Building CXX object src/CMakeFiles/rbind_opencv.dir/types.cc.o
[ 75%] Building CXX object src/CMakeFiles/rbind_opencv.dir/operations.cc.o

One of examples is
/ruby-2.0.0-p353@img-processing/gems/ropencv-0.0.12/ext/src/operations.h:1226:67: error: expected ';' after top level declarator
rbind_cv_FileNodeIterator* rbind_cv_FileNodeIterator_operator_plus+(rbind_cv_FileNodeIterator* rbind_obj);

UPD.

1. Tried to build gem manually, running extconf.rb and rbind.rb manually - all works fine. But when running tests raise error at the same place. Suppose the problem in handling plus+ and minus-

2. Adjusting helper.rb in release published on rubygems.org to accept opencv 2.4.7. Everything works fine and passes all the tests without error. So high chances problem arise due to changes in source after publishing to rubygems.org

Bundle install gives:

I tried ruby 2.7.5 and 3.1.0. Using opencv 4.5.4 on Mac.

1. file_storage.rb
   throws "undefined method `<<' for #OpenCV::Cv::FileStorage:0x007f8ee6031318"

2. find_homography
   throws error "undefined method `_' for #OpenCV::Cv::Point2f:0x007fd97caccaf8"
   Replacing "pt_0.2" with simple "pt" allows to run example successfully

All the rest - works fine. Thanks for great wrapper!

Just wondering if the ropencv gem supports Open CV 3? There are KAZE and AKAZE in there which is useful as SURF/SIFT are patented.

From what I can see currently only OpenCV 2.4.11 is supported.

Am a bit new to this so apologies if I'm asking a stupid question!
