Optical occlusion
WebRetinal artery occlusion refers to blockage of the retinal artery carrying oxygen to the nerve cells in the retina at the back of the eye. The lack of oxygen delivery to the retina may result in severe loss of vision. Download … WebJun 20, 2024 · Its objective is to help the network predict the flow in the occluded regions and rectify the occlusion map at the same time. The basic idea behind the unsupervised optical flow models is to warp the second image toward the first image according to the estimated optical flow.
