WebSep 21, 2024 · The sampling-based matting method is an important method for image matting. There are three key techniques in sampling-based matting: 1) how to build a sample-set; 2) how to travel a sample-set; 3) how to obtain a good sample-pair. Although sampling range has expanded from local to global, the existing approaches to build the … WebDec 25, 2024 · Bayesian optimization is a machine learning based optimization algorithm used to find the parameters that globally optimizes a given black box function. There are 2 important components within this algorithm: The black box function to optimize: f ( x ). We want to find the value of x which globally optimizes f ( x ).
