Optimization of Removed Algorithm in the Grayscale Bitmap Background Impurities Among Traces Identifying

摘要

This paper is about the design of two more optimized grayscale bitmap (BMP) background impuritieseliminating algorithm, and proposes two design ideas of Combination of two algorithms. The essay aims at the gray background bitmap collected from the current identification with traces of impurities, on the basis of the statistic of regional and connected areas. As a result, The overall program operation speed will be greatly improved in the system of traces-identification and face-recognition, image background impurities will be eliminated more effectively and accurately, so that optimal image results will come up.
