HAND GESTURE RECOGNITION BY SCANNING LINE-WISE HAND IMAGES AND BY EXTRACTING CONTOUR EXTREME POINTS

摘要

Apparatus and a method for image recognition are disclosed, in which an image is electronically scanned line-by-line. Each line of pixels is processed and pixels which qualify according to both tonal and positional criteria are selected as contour points. A set of contour points is compared with a stored reference to determine the nature of the image.
