碩士 === 國立交通大學 === 電機與控制工程系所 === 93 === Face replacement system plays an important role in the entertainment industries. Recently, however, most of these are assisted by hand and specific tools. Therefore, there are not many papers in this field. In this thesis, we describe a new face replacement system for automatically replacing a face with image processing. In the system, we segment the facial region by skin color analysis and morphology. Feature detection and connectivity analysis are applied to find candidates of facial feature. Then we combine mouth color analysis to obtaining features of the mouth. The eyes are located by geometric relation with mouth and projection function. We obtain features of the chin by information of gradient and entropy. Then we use the least square method to construct the chin line. We can wrap and locate the target face by feature matching. We extract skin color pixels on face region. We make the skin color of the original face similar to that of the original face by histogram matching. Image blending and smoothing is used to eliminate the seam. As can be seen, the experimental results show that this face replacement system has good performance if both original and target faces are front-facing as long as there are no large variations in illumination and skin tones.
