Kuan Lin, YU Jian-qiao, Wen-Lan Geng, Bin Liao · 2011
This paper proposes an effective image preprocessing chain for estate electron file to eliminate most of the effect of noise and enhance the recognition performance. Owing to its' diversity and particularity, the processing of real estate file images is extremely significant compared with the general images', so a integrated preprocessing chain is firstly applied for images of estate file .It includes image graying and binarization, the smoothing of the images, the removing of separate noise, image correcting and the effective image segmentation. The experimental result shows that this presented chain can effectively process the real estate file images according to its characteristic and achieve a high average precision.
