Efficient Hand Segmentation and Fingertip Detection Using Color Features of Skin and Fingernail

摘要

In this paper, we design a new color space YU_(skin)V_(skin) from YUV color space, based on the principle of skin color with respect to the change of color temperature. Compared with previous work, this color space proved to be the optimal color space for hand segmentation with linear thresholds. We also propose a novel fingertip detection method based on the concomitance between finger and fingernail. The two techniques together improve the performance of hand contour and fingertip extraction in hand gesture recognition.
