Web1) What is the Birchfield-Tomasi metric used in the algorithm ? Every paper relates to a "Birchfield-Tomasi metric" but no one explains what it is and reading the Birchfield-Tomasi paper didn't help me to understand that. 2) How is a window used in that algorithm (what is the operation made with that window)? WebSep 16, 2016 · We used the pointwise Birchfield-Tomasi metric over color data and 8 paths for the optimization, with window size of \(7\times 7\), \(P_1=20\) and \(P_2=100\). The energy terms are summed up obtaining a global cost function \(C^g\) that usually presents a very sharp peak at the minimum cost’s location. crèche micro starWebFeb 27, 2024 · In a low-texture scene, such as an indoor corridor, only a few points of depth can be calculated.
