主　　题：de-watermark text recognition character recognition optical character recognition(OCR)application 

摘      要：When using the current popular text recognition algorithms such as optical character recognition(OCR)algorithm for text images,the presence of watermarks in text images interferes with algorithm recognition to the extent of fuzzy font,which is not conducive to the improvement of the recognition *** order to pursue fast and high recognition rate,watermark removal has become a critical problem to be *** work studies the watermarking algorithm based on morphological algorithm set and classic image algorithm in computer *** can not only remove the watermark in a short time,but also keep the form and clarity of the text in the *** algorithm also meets the requirements that the higher the clarity of image and text,the better the processing *** can process the Chinese characters with complex structure,complicated radicals or other characters *** addition,the algorithm can basically process ordinary size images in 1 s,the efficiency is relatively high.
