First, we perform wavelet transform. Next for edge detecting from detail wavelet coefficient, we use dynamic threshold. By blurring approximate coefficients with alternative heuristic thresholding, achieve effective edge,. Afterward, with ROI technique get binary image. Finally text boxes would be extracted with new projection profile.<\/p>\r\n","references":"[1] Mehmet Sezgin , Bulent Sankur \"Survey over image thresholding\r\ntechniques and quantitative performance evaluation\" Journal of\r\nElectronic Imaging 13(1), 146-165 (January 2004).\r\n[2] Faisal Shafait, Daniel Keysers, Thomas M.
