Hi, i'm working in the spatio temporel interest point, and in order to detect the keypoints , the video have to be matrice (Height x Width x frames) How can i do it? Thank you.
I'm not sure what you're asking. You can provide video by using a video camera to create a video that is stored in a file. Or you can create one manually from a bunch of frames and using the im2frame() function. Or you can "provide" one to your program (i.e. put into a variable in your program) by using VideoReader class, or mmreader(), or avireader().
