Abstract: A method for decoding an image based on an intra prediction, comprising: obtaining a first prediction pixel of a first region in a current block by using a neighboring pixel adjacent to the current block; obtaining a second prediction pixel of a second region in the current block by using the first prediction pixel of the first region; and decoding the current block based on the first and the second prediction pixels.

Abstract: Provided is a personalized node ranking (PNR) system and method using random walk. In detail, a personalized ranking method using random walk includes verifying whether propagation of a positive score or a negative score of a currently-visiting node is trustworthy based on an edge sign between a seed node and a next-visiting node predicted by using a classification model, and when the propagation is trustworthy according to the verification, propagating a score by using a first score propagation method based on balance theory, and when the propagation is untrustworthy according to the verification, propagating a score by using a second score propagation method based on a ratio between a balanced triangle and an unbalanced triangle of a signed network.
