Abstract
Methods and apparatuses of classifying an image as either a text image or a non text image are provided. The method includes converting an input image into an image histogram comprising gray levels and a frequency of the gray levels; analyzing the image histogram to determine a characteristic of the image histogram; and classifying the input image as a text image or a non text image based on the characteristic. The characteristic of the image histogram may include the frequency of the gray levels, a number of peaks, a distance between peaks, and a peak width. The image may be split into blocks and a number of edge pixels determined for each block. The blocks with at least a predetermined number of edge pixels may then be classified. The entire image may then be classified based on the number of blocks determined to be a text image.
