Very good. It is exactly what I wish...and it works. Thank-you.

Ok.

In folder "opencv\sources", I startes command : cmake -G "MinGW Makefiles" . This build Cmake files. But what to do now with this CMake result ? How can I use MinGW in order to compile and link the CMake result ?

Best regards.

Hello, So I have installed MinGW. And when I start the command line "cmake ." in openCv sources folder, cmake doesn't compile for MinGW but for "-- Building for: Visual Studio 9 2008".... How can I "switch" cmake to MinGW ? Best regards.

Switching to OpenCV 3.0.0-tp2 / Version control: 2.4.8, my previous working code using findContours() fails

ret, frame = self.cap.read()
edges = cv2.Canny(frame,100,200)
contours, hierarchy = cv2.findContours( edges, cv2.RETR_TREE, cv2.CHAIN_APPROX_SIMPLE)
>>> too many values to unpack

Best regards

It's ok. I have found the package on SourceForge.

As I need Python lib, I only unpack and copy the file cv2.pyc in python site-package folder. the function boxPoints exists.

But for release, the cv2.getBuildInformation() gives a strange result:

General configuration for OpenCV 3.0.0-tp2 ===== Version control: 2.4.8-3169-g9f8de6

Best regards.

Hello, You're right. It is tutorial

http://docs.opencv.org/trunk/doc/py_tutorials/py_imgproc/py_contours/py_contour_features/py_contour_features.html#contour-features

But, First) I have not found how to know "programatically" the exact version of openCV installed on the computer (I know that I have download the package 2.4.8, but...). Second) I don't know where to find the OpenCV release 3 for Windows and for Raspbian ?

Best regards

Hello, In order to extract the rotated box from a contour, I used followin python script:

box = cv2.boxPoints(rect)

And following error occurs : ''module' object has no attribute 'boxPoints'

Please help me.
