APPARATUS, METHOD AND PROGRAM FOR CALCULATING OBJECT SALIENCY MAP

摘要

PROBLEM TO BE SOLVED: To calculate a saliency map of an object while properly capturing a major object in an image.SOLUTION: An object candidate area extraction section 30 extracts plural object candidate areas from an input image in which object candidates are captured. A spatial overlap degree calculation section 32 calculates a spatial overlap degree on each pair of an object candidate area and another object candidate area for each of the extracted object candidate areas. An object candidate area ranking section 34 carries out ranking of plural object candidate areas on the basis of the overlap degree on each pair which are calculated for each object candidate area. A saliency score calculation section 36 calculates the saliency score of each pixel in the input image by using one more object candidate areas from upper ranking.SELECTED DRAWING: Figure 1
