Title: METHOD AND DEVICE FOR FILTERING REFERENCE SAMPLE IN INTRA-PREDICTION
Abstract:
The present disclosure pertains to a method and a device for filtering a reference sample in intra-prediction, which can: receive an encoded bitstream; acquire information on an intra-prediction mode of a current block from the bitstream; determine a filter on the basis of a signal component of the current block, the width and height of the current block, and a value of at least one reference sample among reference samples adjacent to the current block; generate filtered reference samples by applying the filter to the reference samples; and generate a prediction sample with respect to the current block on the basis of the filtered reference samples and the intra-prediction mode.
