Form recognition preprocessing algorithm based on filtering out text from form images
Ge Guo · Jisuanji gongcheng yu sheji · 2008
Form processing is disturbed by many text strokes points in form pictures.An algorithm for form images preprocessing is presented.The algorithm filters out most text pixels in the pictures before the information of frame lines is detected.Then we prove the algorithm.Theoretic analysis and experiment results show that this algorithm is effectually and exactly to extrude the frame lines,and makes for continue steps of from processing.
