Extract depth using multiple focus levels

WebMay 1, 2024 · For depth-estimation-based methods, researchers extract depth values of sparse pixels with the sharpest image gradient across the focal stack [10], [11], [12], then propagate the depth values to the dense depthmap. All-in-focus image is then reconstructed by extracting the pixels from focal stack according to the depthmap. WebIt proceeds in two stages: Initially we extract a set of possible depth values for each pixel using NCC as a matching metric. We then solve a multi-label discrete MRF model which yields the depth assignment for every pixel. One of the key features in this process is the inclusion of an unknown state in the MRF model.
