Description

Dear OpenCV Team,

The demo "camshift.py" does not work with OpenCV 2.2, however it works with OpenCV 2.1

After the selection of the area, this error is raised:

Traceback (most recent call last):
File "camshift.py", line 116, in <module>
demo.run()
File "camshift.py", line 79, in run
(iters, (area, value, rect), track_box) = cv.CamShift(backproject, self.track_window, crit)
TypeError: <unknown> is not a numpy array

Thanks

Hello, thank you for the fix. I am attempting to patch the OpenCV 2.2 release. Unfortunately I could not locate your specific changes in the trunk.

Please direct/instruct me on how to apply your fix onto the 2.2 release.

Thank you,
Mati
