Statistical model based facial expression synthesis methods are robust and easier to be used in real environment. But facial expressions of human are very various. How to represent and synthesize expressions which is not included in training set is an unresolved problem in statistical model based researches. In this paper, we propose a two step method. At first, we propose a statistical appearance...
Varying illumination condition is a challenging problem for face recognition and synthesis. The illumination re-rendering technique allows aligning the illumination effects of facial images or relighting them as expected. In this paper, we propose an improved illumination re-rendering method based on more accurate mapping of facial images in the parametric illumination space. This will make the parameter-based...
