Patent abstract
A symbol recognition method for increasing the symbol recognition speed by the processor includes the steps of obtaining a pixel density value and an aspect ratio of the symbol image. Then, the center-point value and the corresponding radius value are obtained by a partitional clustering algorithm. In sequence, a pixel density value and the aspect ratio of the under recognized image are obtained, and compared with the values of the symbol image to determine whether the under recognized image is a single symbol image or not.
