Abstract :
In this paper, a noise blobs removing method of LLP based multi-touch system is discussed. By analyzing the structure and contour of human hand and the intensity information of original images, noise blobs of common gestures can be removed through exponential transform of gray level image and convex hull detection. The method is simple and effective that can remove noise points caused by one-man interaction under common gestures.
