Region-of-interest detection apparatus, region-of-interest detection method, and recording medium

A region-of-interest detection apparatus comprising:

• a segmentation unit configured to segment an input image into a plurality of partial regions;
• a setting unit configured to set a background region in the input image;
• a foreground level calculation unit configured to calculate a foreground level indicating a possibility of a foreground based on a plurality of feature amounts of the partial regions and a feature amount of each of a plurality of positions in the input image;
• a saliency calculation unit configured to, based on the feature amount of one of the positions in the input regions and a feature amount of a portion around the position, calculate a saliency indicating a degree of saliency of the position;
• and
• a detection unit configured to detect a region of interest based on the foreground level and the saliency of the position.
