Title:
METHOD, SYSTEM, AND DEVICE FOR HAND RECOGNITION
Document Type and Number:
WIPO Patent Application WO/2017/101380
Kind Code:
A1
Abstract:
A method, system, and device for hand recognition. The method comprises: acquiring a binary image produced by dividing an image on the basis of human skin colors (S1); extracting a contiguous area in the binary image to serve as a contiguous area to be recognized (S2); calculating an eigenvector of a corresponding sample of the contiguous area to be recognized (S3); calculating the distances between the eigenvalue of the contiguous area and an eigenvalue of a hand sample contiguous area and an eigenvalue of a non-hand sample contiguous area (S4); acquiring K samples of smallest distances and determining whether the number of hand samples in the K samples is greater than the number of non-hand samples; and if yes, then determining the contiguous area to be recognized as a hand feature (S5). The technical solution reduces the rate of false negatives of hand feature recognition and facilitates increased accuracy of gesture-based human-machine interaction.
