Crop, resize, transform and much more, all on-demand and AI Powered

thumbor is trusted by hundreds of companies worldwide

                   
and many more!

thumbor is a smart imaging service that enables on-demand cropping, resizing, applying filters and optimizing images.

Cropping photos automatically can be a frustrating experience with severed heads involved. thumbor uses AI for smart detection.

thumbor is an HTTP server and you can create as many different images as you want just by varying path parameters:

http://<thumbor-server>/300x200/smart/thumbor.readthedocs.io/en/latest/_images/logo-thumbor.png

You should see an image of the thumbor logo in 300x200.

Learn more about all you can do in thumbor's documentation.

Upgrade to thumbor 7

Hey @scorphus do you think we can work together to upgrade this to thumbor 7 and python 3?

Adding it to awesome thumbor anyway.

Intermittent segfaults on Ubuntu 14.04

Not sure if this is the right place to raise this, but I've been unable to get the opencv_engine running reliably due to intermittent segfaults in the cv module taking down the whole thumbor process. It's nothing related to a specific file because I can retry and it works fine. I noticed this during load testing so it may be exacerbated during high load.

It took me a while to find the issue, there was nothing relevant in the thumbor logs, but I noticed 502s and dropped/prematurely closed connections in Nginx. Here's the relevant snippet from syslog:

Feb 12 21:48:30 ip-172-17-0-246 kernel: [  775.849915] init: thumbor_worker (1) main process (20820) killed by SEGV signal

I tried with both the python-opencv package and building 2.4.10 from source, but saw the same results. Relevant Python packages:

opencv-engine==1.0.0
thumbor==4.8.6

install error

when I install it with $ pip install opencv-engine
there is an error

Cleaning up...

Storing debug log for failure in /home/xsm/.pip/pip.log

what can I do for it ?

can this repo be compiled to enable opencv to use gpu acceleration?

Support for OpenCV 3.0?

Hello,

OpenCV 3.0 being out and relatively stable, is opencv-engine compatible with this version?

I've tried it on a VM, but ran into some errors. One of them was the import, that I fixed with the following code:

try:
    import cv
except ImportError:
    import cv2.cv as cv
except ImportError:
    import cv2 as cv

But when trying to request an image, I now get the following:

2015-08-12 10:02:39 tornado.application:ERROR Future exception was never retrieved: Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/tornado/gen.py", line 879, in run
    yielded = self.gen.send(value)
  File "/usr/local/lib/python2.7/dist-packages/thumbor/handlers/__init__.py", line 97, in get_image
    engine.load(buffer, self.context.request.extension)
  File "/usr/local/lib/python2.7/dist-packages/thumbor/engines/__init__.py", line 96, in load
    image_or_frames = self.create_image(buffer)
  File "/usr/local/lib/python2.7/dist-packages/opencv_engine/engine.py", line 78, in create_image
    imagefiledata = cv.CreateMatHeader(1, len(buffer), cv.CV_8UC1)
AttributeError: 'module' object has no attribute 'CreateMatHeader'

I'm guessing the engine is not compatible with OpenCV 3.0 at the moment, but is there any plan to make it so? Do you need help in this?

I'm using opencv-engine 1.0.1.

Thanks for any information!

Alpha layer transformed to black on grayscaled images with feature detection

Hi everybody,

We're using thumbor with feature detection but we have problems when we use grayscaled PNGs having an alpha layer. On these images, the whole alpha layer is transformed into black color.

It seems somehow related to this FIXME:
https://github.com/thumbor/opencv-engine/blob/master/opencv_engine/engine.py#L193

Called by:
https://github.com/thumbor/thumbor/blob/bc52ab6bb8934c08d24c89ef5e52f20744468e58/thumbor/detectors/feature_detector/__init__.py#L23

Did anyone also encountered this problem and have clues to fix it?
Thanks by advance.

Edit New issue OpenCV crash with some PNG Files

Hello,

We are using Thumbor for some resizing on Overblog (https://www.over-blog.com/) and it works very well, but we encounter problems with some PNG files.

We are using OpenCV engine because of its speed and smart detection, and we fallback on PIL when OpenCV crash.

Here is the version we use:
Pillow==2.3.2
opencv-engine==1.0.0
pgmagick==0.5.8
thumbor==4.8.2
thumbor-pexif==0.14.1
tornado==3.2.2

Works on Debian 7 with bundled OpenCV 2.4.10.

Here is an example of a PNG: http://img.over-blog-kiwi.com/0/88/72/24/20150107/ob_f75a17_jescharlie.png

We resize with this command:
/unsafe/568x568/http://img.over-blog-kiwi.com/0/88/72/24/20150107/ob_f75a17_jescharlie.png
(I know it's an upscale)

It's the same with downscale: /unsafe/100x50/http://img.over-blog-kiwi.com/0/88/72/24/20150107/ob_f75a17_jescharlie.png

Works very well with PIL.

Thanks for your work and your help.

No longer maintained?

Safe to say this package is no longer maintained in favor of using the queued detectors and https://github.com/thumbor/remotecv ?

2 years of master failing would suggest yes...

No longer maintained?

AttributeError: 'cv2.cv.iplimage' object has no attribute 'tobytes'

Please see: thumbor/thumbor#817

I was not sure where to open the issue, I encounter this error:

does opencv engine support jpeg2000 format?

I see that there is a thumbor plugin for jpeg2000 (https://github.com/thumbor/thumbor-plugins/wiki/JPEG2000). However it seems like it will only work with PIL, and hence pil engine. Would it be possible to support jp2 format with opencv engine as well?

Improve opencv engine to support RGBA

Handle PNGs with alpha channel.

OpenCV engine seems to strip ICC profile by default

Without using the strip_icc filter, the OpenCV engine seems to incorrectly strip the ICC profile data.

Using non-image url for image in watermark filter crashes the server instead of giving 400

I am using https://github.com/APSL/docker-thumbor to run thumbor.

If you notice the process just died after trying to handle the request.

so, opencv engine crashes trying to open html file as image https://github.com/thumbor/opencv-engine/blob/master/opencv_engine/engine.py#L80

import cv
f = open('index.html', 'rb')
buf = f.read()
print(buf[0:32])
# <!doctype html><html itemscope="

imagefiledata = cv.CreateMatHeader(1, len(buf), cv.CV_8UC1)
cv.SetData(imagefiledata, buf, len(buf))
img0 = cv.DecodeImageM(imagefiledata, cv.CV_LOAD_IMAGE_UNCHANGED)

# Segmentation fault (core dumped)
# python[11900]: segfault at 8 ip 00007f0e56a346c9 sp 00007ffd741c4e30 error 4 in cv2.so[7f0e569fc000+151000]

When do I need this?

As a new user, I am missing a little documentation when I should use this.

• Which minimum Thumbor version is required to use this engine?
• Up to wich version was this engine included in Thumbor?
• Which Thumbor features require this engine to be installed?

ENGINE = opencv_engine with detectors logs "error during face detection"

OS:
Ubuntu 16.04

List python packages:

In thumbor.conf, I have setup the following detectors:
DETECTORS = [
'thumbor.detectors.face_detector',
'thumbor.detectors.feature_detector',
]

When I use the PIL engine (in this case I use Pillow-SIMD but with PIL the same result), everything works fine:
ENGINE = 'thumbor.engines.pil'

But when I change to use OPENCV engine, the detectors don't work

http://<thumbor_server>/unsafe/100x200/smart/https://www.dzoom.org.es/wp-content/uploads/2013/04/retratos-fotograficos-1-734x489.jpg

and I see the following in the console output:
2018-01-05 09:41:22 thumbor:WARNING Error during face detection; skipping to next detector
2018-01-05 09:41:22 thumbor:WARNING Error during feature detection; skipping to next detector

Support for GPU acceleration?

Hi, is there support for GPU acceleration in the OpenCV engine?

I tried the OpenCV engine on a GPU instance on AWS EC2, with CUDA drivers installed, but saw an actual drop in performance as compared to the default pil engine when doing simple resizes.

AttributeError: 'module' object has no attribute 'DecodeImageM'

I get the following error (I use CentOS 6.4):

File "/usr/lib/python2.6/site-packages/opencv_engine/engine.py", line 61, in create_image
img0 = cv.DecodeImageM(imagefiledata, cv.CV_LOAD_IMAGE_UNCHANGED)
AttributeError: 'module' object has no attribute 'DecodeImageM'

how can I solve it?

Install success but has errors

Went ahead to try, I am using amazon ec2 ubuntu 13.10. I have the same version at home and it works. But now this is the error.
