I'm trying to debug a video decoder device driver on a DM642 system that uses TI's class/IOM driver model under BIOS and in which the class driver is GIO. When the application first starts a video capture, it calls GIO_submit() to obtain a buffer of data, but the function call isn't returning, i.e., it appears to block. The problem is, according to the documentation, the function should ru...

Hello, I'm using phase correlation to perform motion estimation on video and am trying to find some sort of metric for the quality of a peak (which corresponds to a candidate motion vector) in a given phase correlation block. I know that performing phase correlation on duplicate images gives a result that has a peak at (0, 0) with magnitude 1 and 0 elsewhere. Obviously, in real video the...
