DSP Fast Processing Technology Based on BP Algorithm

Image recognition has always been an important research topic in the field of pattern recognition. This article uses the printed character recognition of bills as the research background. Through the detailed analysis of the recognition process, some preprocessing algorithms are selected and implemented, including image enhancement, binarization, filtering, character cutting, skew correction, etc. Finally, transplant each algorithm to the simulation platform, mainly for BP algorithm, according to the characteristics of DSP, optimize from two aspects of compilation options and source code to meet the requirements of fast processing. Finally, the requirements of better recognition effect and fast processing speed are realized.
