Gray image recognition using Mahalanobis distance invariable
Zhang Li · Journal of Zhejiang University of Technology · 2001
This paper applies mahalanobis distance vector as the invariable in recognizing the object in the image. The problem of object division in the process of computing mahalanobis distance is discussed. Based on the gray scale of object image, a new division method is brought forward. Results of experiments proved that this method applied in object recognition has good adaptability and small error when the object moves and rotates in the sight. The new method brought by this paper leads to divide the point set of object image directly according to its gray scale. This method gets rid of the difficulty of the realization of division based on topology, and realizes the automation of image recognition based on mahalanobis distance vector.
