Optical flow vs frame sampling
WebJun 25, 2024 · Then, change the number of echoes to the number of frames after the current one you want it to be blended with. The decay is the percentage the frame’s opacity decreases by. So, .50 means that the current frame will be 50% opacity one frame from now and 25% opacity the next and so on (assuming you starting intensity is 1). WebAug 10, 2007 · The higher M is, the better; it should at least be 16 otherwise the optical flow estimates may not be very accurate. Using M=16 we get a sampling_rate of 16/0.2=80Hz. The next thing you want to consider is what is the frame duration ( frame duration = 1/frame rate) of the images that would be input to the algorithm.
