Fast DCT(Discrete Cosine Transform) 8-bit decoder

Fast DCT 8-bit decoder

Skew detection and correction is very important task before pre-processing of an image and it is a major problem in scanned documents, if it not detected correctly it will lead wrong result in future during image analysis. During the scanning of th
