The gray image is generated according to the real-time depth value on transporter in underwater terrain auxiliary navigation. The accurate position is obtained by matching to the water depth map stored on the computer of the carrier. Thus, the image recognition is an important problem. An advanced matching method based on related pixel grayscale is put(More)
A novel shape recognition method based on fuzzy distance measure is proposed. A fuzzy set is defined on the feature vector space according to each training class, so the distance between an unknown shape and the class centroid is measured by a fuzzy distance based on the membership function. Another significant contribution of this paper is the method of(More)
