In this paper a structural method for recognizing Persian handwritten digits is proposed. Because of different styles in some Persian digits, in this work they were divided into 18 classes. In recognition algorithm a heuristically designed binary decision tree recognizes the digits via a series of initiative structural features. The research aim was to choose those structural features that were useful both in terms of accuracy and speed. A set of 6180 digits was used for the test. About 93.1 percent of the digits were recognized correctly. The recognition average speed of this algorithm is 24 digits per second on a 486DX4 100 MHZ.
