Abstract (in Japanese) (See Japanese page) 
(in English) We introduce a technique which extracts finger nail areas from a hand image at high speed and high accuracy, for the purpose of improvement of accuracy in 3D hand pose estimation. In the system, first, a hand image is converted into original RGB, YIQ, HSV, HLS, L*u*v* color-coordinate systems and select one where two regions are comparatively in the two-dimension, so as to select the proper color-coordinate system for extraction of the finger nail areas. As the result, HLS color system which is composed of hue, saturation, and brightness showed a good performance. Next, we introduced a the rectangle frame with upper and lower limits at each two axes where all pixels are judged as finger nail area. Our method showed that the number of the areas and each centers can be extracted at high accuracy when these limits are selected properly.
