Face Segmentation Using Novel Skin-Color Map And Morphological Technique

The paper proposes a novel algorithm to dynamically define the Region of Interest (ROI) videophone application. The algorithm uses the color information Hue and Cr to find the skincolor pixels and also use range of threshold obtained from red and blue components in normalized RGB color space to remove nonskincolor pixels because the human skin tends to have a predominance of red and non-predominance of blue. Post-processing is used to remove such noises by a morphological operator. Moreover, the algorithm performs temporal filtering to remove skin-color pixels that immediately appear from frame to frame by using object tracking process to perform as memory for collecting skin-color objects obtained from previous frame to guide the next frame. The experimental results confirm the effectiveness of the proposed algorithm. Keywords—face segmentation, human skin segmentation, video object segmentation, Region-of-Interest (ROI) video coding.
