PROBLEM TO BE SOLVED: To provide an error-proof method for detecting main subject matter. SOLUTION: This invention provides a method for detecting the subject matter regions in a digital color image having pixels of (red, green, blue) values. The method comprises a step of; assigning to each pixel a belief value belonging to the subject matter region based on color and texture features; forming spatially contiguous candidate subject matter regions by thresholding the belief value; analyzing the spatially contiguous regions based on one or more unique characteristics of the subject matter to determine the probability that a region belongs to the subject matter; and generating a map of detected subject matter regions and associated probability that the regions belong to the subject matter.
