<p><P>PROBLEM TO BE SOLVED: To discriminate the position of an object by analyzing a pickup image containing photographic subjects including a person and a landmark-like object representing the spot. <P>SOLUTION: An object search zone extraction section 303 extracts an object search zone by excluding a face zone and a body zone from image data. A remarkable zone candidate extraction section 304 extracts plural remarkable zone candidates from the object search zone. A color-uniqueness calculation section 305 discriminates color information on each pixel of the object search zone and calculates quantitatively a color-uniqueness of each color on the basis of the frequency of the color and a distance from another color. An presence probability calculation section 307 calculates the presence probability of an object zone for each block unit. An object zone discrimination section 308 calculates likelihood of each remarkable zone candidate as a remarkable zone and determines the most likely remarkable zone candidate to be the object zone. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
