Abstract
A method of photo/text separation using path frequency of pixel intensities is disclosed. It divides an original image into n*n pixel blocks and records the path conditions satisfied by the intensities of consecutive two pixels. From the statistical analysis of the path appearance frequency, the method determines the text/photo types in the pixel block, thereby determining the output type of the whole original image.
