Abstract

Provided is a method and apparatus for performing intra-prediction using an adaptive filter. The method for performing intra-prediction comprises the steps of: determining whether or not to apply a first filter for a reference pixel value on the basis of information of a neighboring block of a current block; applying the first filter for the reference pixel value when it is determined to apply the first filter; performing intra-prediction on the current block on the basis of the reference pixel value; determining whether or not to apply a second filter for a prediction value according to each prediction mode of the current block, which is predicted by the intra-prediction performance on the basis of the information of the neighboring block; and applying the second filter for the prediction value according to each prediction mode of the current block when it is determined to apply the second filter.

Description

[0001] This patent application is a divisional application of the following invention patent applications: [0002] Application number: 201180028539.2 [0003] Application date: April 11, 2011 [0004] Invention Title: Method and device for performing intra prediction using adaptive filters Technical field [0005] The present invention relates to video encoding, and more specifically, to a method for performing intra-prediction by applying an adaptive filter to surrounding pixel values ​​of a block to be predicted or predicted pixel values ​​of a current block Method and equipment. Background technique [0006] With the recent emergence of digital television (TV), etc., technologies in the fields of broadcast TV and home entertainment are being rapidly developed. The standardization of video compression technology is commercializing technologies in the field. For video compression, the ITU-T (International Telecommunication Union-Telecommunications) H.263 standard is being widely u...
