The Extracting And Processing Of Printing Characters In Nature

The processing and recognizing of Characters is a research hotspot in the current field of artificial intelligence, this paper presented the Characters processing system based on the BP++ neural network after analyzing the foreign and domestic research situations.The image processing have many new characteristics contrasting with pattern recognition.(1)The quantity of data is huge.(2)The class of output is more than pattern recognition.(3)the characteristics of moving equivalenceIn order to apply neural network in the new area, The system of the character processing system based on BP + + neural network have improved in several aspects to become a new system that can do well in image processing.(1)This arithmetic improved on increasing convergence speed. This arithmetic's theory bases were credibility and it was convenient useful, so it had practical engineering application value.(2) The structure of traditional neural network was changed to suit for the claim of image processing.The new structure recommend the structure of true neural network in accordance with the characteristics of moving equivalence and The large number of output class.
