Claim Text:
1. An information processing apparatus, comprising: a memory storing instructions; and at least one processor configured to process the instructions to: receive an input image, calculate a local variation of a first pixel in the input image based on a difference in pixel value between the first pixel and a surrounding pixel of the first pixel, calculate, based on gradient values for pixel values of the input image, a region attribute value associated with each pixel of the input image, wherein the region attribute value indicates a likelihood that a pixel belongs to a predetermined region in the input image, calculate, based on the region attribute value, a regularization strength for each pixel of the input image, calculate a filter coefficient for suppressing a variation between neighboring pixels in the input image based on the local variation and on the regularization strength, create a second image by degrading the input image, calculate a reconfiguration error between the input image and the second image, and create a first provisional image based on the filter coefficient and the reconfiguration error.
