Optical flow movement endoscope code
WebOptical flow models take two images as input, and predict a flow: the flow indicates the displacement of every single pixel in the first image, and maps it to its corresponding pixel in the second image. Flows are (2, H, W)-dimensional tensors, where the first axis corresponds to the predicted horizontal and vertical displacements.

WebMar 14, 2013 · 1 One very straightforward way to go about it will be to provide the algorithm with a key frame which has the ground truths. What it means is that, segment the first frame manually (you could use a grabcut here) and then propagate the segmentation to subsequent frames using optical flow. WebBy training the network with optical flow, the network learns which pixels of the optical flow are important and weigh them accordingly. The file frames_to_opticalFlow.py is used to generate a dense optical flow image from two consecutive frames using the openCV function cv2.calcOpticalFlowFarneback(). The optical flow looks like this: Data ...
