Method and related device for providing video encoding and/or decoding using reference values

Abstract

An encoded video sequence comprising a plurality of images may be decoded. A first neighboring block and a second neighboring block of an image of an encoded video sequence may be provided. A pixel line comprising pixels of the first block and the second block may be defined, extending across a boundary between the first block and the second block. The first reference value may be calculated based on a first pixel of the pixels from the first block. A second reference value may be calculated based on a second one of the pixels from the second block. A filtered pixel value for each pixel in a line of pixels between the first pixel and the second pixel may be calculated using interpolation based on the first reference value and / or the second reference value. A filtered block may be generated using the filtered pixel values, and a decoded video sequence may be generated based on the filtered block.

Description

technical field [0001] The present disclosure relates generally to video processing, and more particularly, to video encoding and / or decoding and related methods and devices. Background technique [0002] A video sequence is a series of images (also called pictures), where each image includes one or more components. Each component can be described as a two-dimensional rectangular array of sample values. An image in a video sequence may comprise three components; a luma component Y (where the sampled values ​​are luma values) and two chrominance components Cb and Cr (where the sampled values ​​are chrominance values). The dimensions of the chroma components may be 1 / 2 of the luma components in each dimension. For example, the size of a luma component of a high definition HD image may be 1920x1080, and each chroma component may have a dimension of 960x540. Components are also sometimes called color components. [0003] A block is a two-dimensional array of samples (also ca...

Problems solved by technology

[0040] However, deblocking from H.264 and / or HEVC may not sufficiently reduce / remove strong blocking artifacts

One problem with the strong deblocking filter in JCTVC-F198 is that it can have a very strong low-pass filter effect for all filtered samples

Also, the decision to use a filter may require computing the variance over 16x16 blocks, which can be complicated
