In this paper, the functional commands based on hand gesture are designed by Hu moments and contour sequence moments, which are invariant to the translation, rotation and scale of a hand gesture. First, the original image with a hand gesture is transformed into the color space of YCrCb. The segmentation of the skin-like objects is obtained by suitable thresholds of Cr and Cb. In sequence, the morphological...
A DSP-based design method of finger vein recognition was proposed, and a finger vein authentication system FV-1 was developed. In this system, finger vein images were captured with infrared, and normalized through rotation correction, then they were segmented and thinned to wipe off useless segments. Finally, features on vein points were obtained and two finger vein images were matched in view of...
