Abstract:
1. An image processing apparatus comprising: a conditional probability calculating unit, implemented at least by a hardware including a processor, and which calculates, as a conditional probability, a probability of existence of an attribute with regard to each region in an input degraded image, for each attribute, i.e., an element defined in advance as an element that can exist within the degraded image; an optimization function determining unit, implemented at least by a hardware including a processor, and which determines an optimization function using a candidate of a restored image as a variable and yielding a smaller value as the candidate of the restored image is closer to a true restored image by using a conditional probability calculated by the conditional probability calculating unit with regard to each region in the degraded image for each attribute, a-priori knowledge defined as a conditional probability of appearance of an attribute in a region of the candidate of the restored image when there is the attribute in the region, and the input degraded image; and a restored image determining unit, implemented at least by a hardware including a processor, and which identifies the candidate of the restored image with which the optimization function yields a minimum value, and adopting the candidate as the restored image of the degraded image, wherein the conditional probability calculating unit, for each region and for each attribute,
