Abstract
The present invention makes it possible to estimate, with high precision, a candidate region indicating each of multiple target objects included in an image. A parameter determination unitdetermines parameters to be used when detecting a boundary line of an imagebased on a ratio between a density of boundary lines included in an imageand a density of boundary lines in a region indicated by region informationindicating the region including at least one of the multiple target objects included in the image. A boundary line detection unitdetects the boundary line in the imageusing the parameter. For each of the multiple target objects included in the image, the region estimation unitestimates the candidate region of the target object based on the detected boundary line.
