|Title:||Edge-preserving prefiltering for document image binarization||Authors:||Fan, L.
|Issue Date:||2001||Citation:||Fan, L.,Tan, C.L.,Fan, L. (2001). Edge-preserving prefiltering for document image binarization. IEEE International Conference on Image Processing 1 : 1070-1073. ScholarBank@NUS Repository.||Abstract:||We propose a novel coplanar filter, which exploits the coplanarity of gray-level distribution of neighboring pixels, to pre-filter the document images. Experiments show that the proposed filter exhibits the following desired properties for document image binarization: (1) impulsive noise removal, (2) piecewise smoothing, and (3) sharp edge preservation.||Source Title:||IEEE International Conference on Image Processing||URI:||http://scholarbank.nus.edu.sg/handle/10635/40219|
