COMPUTER READABLE MEDIUM, IMAGE PROCESSING APPARATUS, AND IMAGE PROCESSING METHOD
First Claim
1. A computer readable medium storing a program causing a computer to execute a process for image processing, the process comprising:
- calculating, on the basis of image feature information of a plurality of image areas each set with a classification information item, a probability distribution of the image feature information for each classification information item;
acquiring a target image;
calculating an evaluation value of each of pixels included in the target image relating to a specified classification information item, on the basis of the image feature information of an image area including the pixel and the probability distribution of the image feature information calculated for the specified classification information item; and
extracting, from the target image, an image area relating to the specified classification information item, on the basis of the evaluation value calculated for each of the pixels included in the target image.
