Method and apparatus encoding and/or decoding image by using diffusion properties of the image

A method of encoding a moving picture, the method comprising:

• predicting, by a processor, a value of a current pixel of a current image from among a plurality of images constituting a moving picture from at least one neighboring pixel from among neighboring pixels located in various directions toward the current pixel, based on the variations between values of the neighboring pixels;
• generating a predicted image of the current image based on the predicted value of the current pixel;
• and
• encoding the residue between the current image and the predicted image,
• wherein the predicting of the value of the current pixel comprises:
• calculating a correction value of the predicted value of the current pixel by using the variations between the values of the neighboring pixels;
• and
• compensating for the predicted value of the current pixel by using the correction value.

A non-transitory computer readable medium having recorded thereon a computer program for executing a method of decoding a moving picture, the method comprising:

• decoding a bitstream in order to reconstruct the residue between a current image from among a plurality of images constituting the moving picture, and a predicted image of the current image;
• predicting a value of a current pixel of the current image from at least one neighboring pixel from among neighboring pixels located in various directions toward the current pixel, based on the variations between values of the neighboring pixels;
• and
• generating a reconstructed image of the current image by combining the reconstructed residue with the predicted image containing predicted pixel values,
• wherein the predicting of the value of the current pixel comprises:
• calculating a correction value of the predicted value of the current pixel by using the variations between the values of the neighboring pixels;
• and
• compensating for the predicted value of the current pixel by using the correction value.
