Gwang-Soo Hong, Min-Su Koo, Avishek Saha, Byung‐Gyu Kim · 2016
We propose new local stereo matching method based on weighted guided image filtering (WGIF). We utilize the WGIF by using local variance window of pixel in a guidance image which is applied to calculate local weights for cost volume filtering. The proposed method shows better performance than other cost filtering algorithms.
