Research On Hand Shape Recognition System Based On DSP Embedded Operation System

With the rapid development of economic and social, science and technology constantly updated,the awareness of protection personal information has been enhanced. The demands of identification citizenship of country departments are increasing. Due to the size of a human hand is uniqueand invariant, thus becoming the main features for personal identification.In recent years, the hand shape recognition productis smaller, and easier to carry. With low-cost development demand, the hand shape recognition system based on embedded DSP was studied. This article choose DM642+TVP5150A combination with PC as the table for the hand shape recognition system. Particular, in the image matching stage, we use the size of the hand as features in the development process, and the image processing algorithm has been optimized. Experimental results show that using DSP processing power, this hand shape recognition system can quickly get the hand shape recognition certified results, while reaching93.77%recognition rate, and the less number of hand-shaped feature selection is conducive to data storage.
