  • Patent number: 9189861
    Abstract: An image processing device has an affinity calculating unit that handles each pixel in an image or each region including a plurality of pixels joined together, as a unit component, and determines a first affinity between each of the unit components and one of the unit components which is located in a periphery region of the image, a foreground region identifying unit that identifies, as a foreground region, a region made up of one or more of the unit components whose first affinities calculated by the affinity calculating unit are lower than a preset threshold, and a saliency measure output unit that determines a second affinity between each of the unit components in the image and the foreground region identified by the foreground region identifying unit, and outputs the second affinity as a saliency measure for each unit component.

  • Patent number: 9020270
    Abstract: An image processing device configured to detect a salient region from an image has a pixel small-region image generating unit that generates a pixel small-region image using, as a unit, a pixel small region made of pixels adjacent to one another and whose luminance values or chromaticity are similar, from the image, a prior probability calculator that calculates prior probability of likelihood of the salient region for each of the pixels of the image, a region generating unit that generates a salient-region-containing region having high possibility of containing a salient region on the basis of a corner point extracted from the image, and a likelihood calculator.
