Image segmentation apparatus, method and program

摘要

An image processing apparatus includes a probability value calculator (16) that calculates, based on color feature data of a pixel included in an image, respective probabilities that the pixel belongs to a specific area and a non-specific area; a weighted edge intensity calculator (17; 21) that calculates a weighted edge intensity between neighboring pixels based on pixel values and color feature data of the pixel included in the image and a neighboring pixel of the pixel; an energy function creator (18) that uses the probabilities and the weighted edge intensity to create an energy function expressed by a result of an area determination of the pixel; and an area divider (19) that divides the image into the plurality of areas based on the energy function.
