Abstract
An image coding and decoding system is provided that includes an image coding apparatus and an image decoding apparatus. The image coding apparatus includes a coding unit that codes an input image to obtain a first coded image, a first decoding unit that decodes the first coded image to obtain a reconstructed image, and a determining unit that determines a first filter setting parameter for the input image, a first comparing unit that compares a difference of pixel values with the threshold value, and a first removing unit that removes a coding. The image decoding apparatus includes an obtaining unit that obtains a second filter setting parameter, a second decoding unit that decodes the coded image to obtain a reconstructed image, a second comparing unit that compares a difference of pixel values with the threshold value, and a second removing unit that removes a coding distortion.
