plstcharles / litiv Goto Github PK

Hi, I'm testing the library in MSVS2015.

When I run litiv_sample_changedet with some sample image sequences (build is all fine, no errors, no warning, build under Debug x64), the program crashes on this line..

and the debugger brought me to this file and said illegal instruction (something related to the memory)

How can I fix it? Or is there other way to get the instance of the background subtraction method.
( and BTW, when I compile the code using Release x64, the program crashes without running a single line of code, do i need some extra configuration?)

Hi, I'm using Ubuntu 14.04 LTS and I direct import the codebase into Clion 2016.2.3, and then the following errors showed up.

but I think I've properly installed the opencv, Because I can run some opencv example program successfully.

And when I cmake in terminal, it seems opencv was found.

This is related to a dataset issue, forgive me if this is not the right place to ask.

I have compiled and installed this repository with no issue.
I am now trying to run something which calls this library and acts on the LITIV2018 dataset (Online Mutual Foreground Segmentation for Multispectral Stereo Videos) located here from the datasets page.

For vid04, I am getting this assertion error found in include/litiv/datasets/impl/litiv-stcharles2018.hpp:

lvAssert__(vsLWIRFramePaths.size()>0u && vsLWIRMaskPaths.size()<=vsLWIRFramePaths.size() && vsLWIRGTPaths.size()<=vsLWIRFramePaths.size(),"bad input lwir packet count for sequence '%s'",this->getName().c_str());

I found the following:

• vsLWIRFramePaths.size() = 1438 (lwir)
• vsLWIRFramePaths.size() = 1836 (lwir_masks)
• vsLWIRGTPaths.size() = 118 (lwir_gt_disp)

Particularly, the lwir_masks folder has all 0-1835 images, but the lwir folder is immediately missing 0, 7, 16 etc.

Am I missing something?

Building the framework on Windows using MSVC2015 and CUDA may cause a unit test to fail in release mode. The test in question:

65>        Start 17: litiv_utest_imgproc_global
65>  17/30 Test #17: litiv_utest_imgproc_global .......***Failed    9.13 sec

Will have to investigate further later on.

Try to compile on Mac OS X 10.11 with GNU GCC 5.3, everything is fine with cmake.

But when I start to make, the following error occurs.

I think we should
change "http://bitbucket.org/eigen/eigen/get/3.3.4.zip" in 3rdparty/eigen3/CMakeLists.txt to
"https://gitlab.com/libeigen/eigen/-/archive/3.3.4/eigen-3.3.4.zip" .
Because, the first address respond "Repository eigen/eigen not found".

the image origina size is 1920 x 1080,I make it risize to 320x240 (QVGA),the it about 0.8 second per frame at Intel i7 CPU,the paper said that the speed is 22 frames per second Intel i5 CPU,can you help me to enhance the processing speed?

Attempted to build without any bells or whistles:

$ mkdir build
$ cd build
$ cmake ..
$ make

But fails with:

Hi, I was trying to build with GCC 4.8.4 on Ubuntu 14.04

When I try to make, there was following error

How can fix I it? Thanks

it‘s in DistanceUtils.h.

my video is single channel,when it run to about 500 frames the error occured,"there "CV_Assert(nChannels>1 && nChannels<=4)",can you teach me how to fix this problem?

Hello~
I want to use your algorithm to detect stationary obj(like the cargo that fell from truck to the ground ),so I make the learningRateOverride=0(not update the bg model at all) to detect the stationary foreground.But the staionary foreground still get into the bg model which lead the stationary foreground can't be detect.So sincerely hope you to help me,can you give me some advice about stationary objection?

                                                                                                                Thanks!
                                                                                                                Kind regard.

Bonjour,

Thanks a lot for your great contribution.

I notice that opencv >= 3.0.0 is required, but I failed to cmake with a version 4.5.2 of opencv. I would like to know if it supports opencv 4.

Merci!

Hi when I compile the code in Visual Studio 2015 after cmake

I get 2 types of errors

1. "illegal indrection" in LBSP.hpp file

2. some functions or variables are not member of cv

Any idea how to fix it?

Hello，I‘m still study your PAWCS，I want to find a way to skip the bg model update，but I’m getting in trouble with the code......I use the PAWCS with bgslibrary，can you give me some annotations about the function “void BackgroundSubtractorPAWCS::apply()”? or some simple explain of the Looping statements？Please，need your help
