However, the dense optical flow is brightness sensitive and only can handle tiny movements with redundant information [ 15 ].
WebMay 10, 2024 · The optical flow method based on the tissue intensity constant assumption between adjacent frames for tracking motion is able to acquire the flow field information for each pixel with a sub-pixel precision, achieving high accuracy with fast execution time [ … WebIn image-guided surgery, endoscope tracking and surgical scene reconstruction are critical, yet equally challenging tasks. We present a hybrid visual odometry and reconstruction framework for stereo endoscopy that leverages unsupervised learning-based and traditional optical flow methods to enable concurrent endoscope tracking and dense scene …
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.
