2015-05-01 04:25:31 -0600 | asked a question | goodFeaturesToTrack returns 2 channel image and can't be imshowed Hi, I'm using goodFeaturesToTrack() method to locate corners from an image. However when I try to view the image, using imshow(), I get an error: OpenCV Error: Bad number of channels (Source image must have 1, 3 or 4 channels) in cvConvertImage Here is the code: goodFeaturesToTrack takes in only a 1 channel image and outputs a 2 channel image. How can I convert the 2 channel to 3 channel or is there an alternative for imshow? |
