2015-06-08 06:45:14 -0600 | commented answer | Face detection (haarcascade) OpenCV Python Loading the cascade can silently fail if the file is not found. Can check with: assert(not face_cascade.empty()). I would prefer this raised an Exception when not found because it tripped me up a few times. |

2015-06-08 03:43:06 -0600 | answered a question | meanshift working only with .avi not with webcam why???? I tried your code and it worked for me - the box moved with a camera feed. Perhaps your lighting is poor so that the detection failed. |
2015-06-08 03:38:24 -0600 | answered a question | Face detection (haarcascade) OpenCV Python Your snippet tries to do more than detect the face. If just trying to get the box working I suggest you get a simple example working first, like this to put a box around the detected face: |
2015-06-08 03:26:14 -0600 | answered a question | Is c++ better suited than Python for real-time applications? I find if the application can be built largely using the existing opencv methods, which wrap the C implementations, then no problem. However if I need to implement my own per pixel algorithms then much faster to drop down to the C interface. |

2015-06-08 03:07:10 -0600 | asked a question | How to determine when CamShift failed? How to determine when CamShift failed to confidently find the new location? Previously with meanShift I checked the return value for the number of iterations to converge, and if it reached the maximum set in criteria then I assumed this was not a match: However with CamShift the return value is no longer the number of iterations: The documentation says this method returns:
I am using version 3 so I guess is not the old version. Is there a way in version 3 to find the number of iterations to converge? Or a better way to determine whether camshift failed? |
