Green Screen Matting
An Implementation of Green Screen Matting by Color Removal and Bayesian Matting
This is an implement of Green Screen Matting through two methods: One is directly remove the pixel whose rgb value is close to green, and the other uses bayesian matting of paper "A Bayesian Approach to Digital Matting".
Prerequisites
OpenCV 3.0+ and Eigen is required.
images
