Face Highlights Removal and Relighting Algorithm Based on Improved Phong Illumination Model
Aiming at the problem that the current face relighting algorithm can not accurately reflect the face reflection,a face image specular removal algorithm and a relighting algorithm based on the improved Phong illumination model are proposed.The algo-rithm includes three parts.1)According to the illumination model,rendered synthetic data to train the neural network to remove highlights.2)The semi-supervised learning is used to transfer the ability of specular removal to real faces.3)After specular remov-al,face image is decomposed into components related to illumination and component unrelated to illumination.The component relat-ed is replaced to illumination ande the image is recombined to achieve face illumination.Experimental results show that the im-proved algorithm can improve the relighting accuracy and visual effect.
