Fixes 95% of the compatibility issues between opencv2 and opencv3. This is done by remapping some of the API in opencv2 to the new, opencv3 style. That way, code written targeting opencv3 will work in opencv2.
Cases in which the function signatures have been changed in opencv3 (e.g. cv2.kmeans) are impossible to fix with this approach. Detection of the current opencv version is facilitated using the added convenience functions is_cv2() and is_cv3().
The following things have been fixed - use the opencv3 version even if you run opencv2:
| opencv2 | opencv3 | |
|---|---|---|
| property names | cv2.cv.CV_* |
cv2.* |
| fourcc | cv2.cv.CV_FOURCC |
cv2.VideoWriter_fourcc |
