A study on face recognition by extracting CT-based color values

This is basic research for extracting face by analyzing color values, and the purpose of this study is to secure expression data with more clear color values extracted by the light sources. For this purpose, how to apply CT algorithm that processes color values efficiently by the light to the existing color value analysis algorithm (RGB. YcbCr, HIS), was suggested. While designing the order of color-based facial expression recognition tracking in 6 steps and applying this to the program, this study assured the efficiency of the detection area. The result shows that the facial region becomes relatively distinct when illumination is focused exclusively on the facial region, than under the global illumination condition.
