METHOD AND APPARATUS FOR INTRA PREDICTION USING AN INTERPOLATION FILTER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18460607 titled 'METHOD AND APPARATUS FOR INTRA PREDICTION USING AN INTERPOLATION FILTER

Simplified Explanation

The abstract describes a method for video coding that involves applying an interpolation filter to reference samples during an intra-prediction process of a block. The interpolation filter is selected based on a subpixel offset between the reference samples and the samples to be predicted, and the size of the main reference side used in the process is determined according to the length of the interpolation filter and the intra-prediction mode that provides the greatest non-integer value of the subpixel offset.

Original Abstract Submitted

Provided are a method, an apparatus, a computer program product and a non-transitory computer-readable medium for video coding. The method comprises performing an intra-prediction process of a block comprising samples to be predicted, wherein an interpolation filter is applied to reference samples of the block during the intra-prediction process of the block. The interpolation filter is selected on the basis of a subpixel offset between the reference samples and the samples to be predicted, and a size of a main reference side used in the intra-prediction process is determined according to a length of the interpolation filter and an intra-prediction mode that provides, out of a 10 set of available intra-prediction modes, the greatest non-integer value of said subpixel offset, wherein the main reference side comprises the reference samples.
