Consequently, the reconstructed pixels contain quantization noise that in-loop filters like DBF, SAO, and ALF attempt to suppress (e.g., which may become apparent from blocking artifacts between cells, ringing artifacts, sharp edges, etc.)

Embodiment Construction

[0058]The following description is made with reference to the accompanying drawings, which form a part of this invention and show by way of illustration specific aspects in which the invention may be practiced. It is to be understood that other aspects may be utilized and structural or logical changes may be made without departing from the scope of the present invention. Accordingly, the following detailed description is not to be taken in a limiting sense, since the scope of the invention is defined by the appended claims.

[0059] For example, it will be understood that a disclosure related to a described method is equally applicable to a corresponding device or system for performing the method, and vice versa. For example, if certain method steps are described, a corresponding device may include means for performing the described method steps, even if such means are not explicitly described or illustrated in the figures. Furthermore, it should be understood that the featur...

Abstract

The invention relates to a device (100) for encoding a current video block of a frame of a video signal, wherein said current video encoding block comprises a plurality of pixels, each pixel being associated with a pixel value. The device (100) includes: a reference pixel unit (101), configured to generate a plurality of auxiliary reference pixel values ​​based on a plurality of main reference pixel values, wherein the plurality of main reference pixel values ​​are identical to those located in the current video coding block Multiple primary reference pixels in adjacent video coding blocks are associated, and the reference pixel unit is used to generate each of the auxiliary reference pixel values ​​based on two or more primary reference pixel values ​​in the primary reference pixel values An auxiliary reference pixel value; an intra-frame prediction unit (103), configured to intra-frame perform intra-frame prediction on pixel values ​​of pixels of the current video encoding block based on the plurality of main reference pixel values ​​and the plurality of auxiliary reference pixel values predict.

Description

technical field [0001] The present invention relates to the field of video coding. More particularly, the present invention relates to an apparatus and method for intra-prediction of a video encoding block, and an encoding apparatus and a decoding apparatus including such an intra-prediction apparatus. Background technique [0002] Digital video communication and storage applications are implemented by a wide variety of digital devices such as digital cameras, cellular radiotelephones, notebook computers, broadcast systems, video conferencing systems, and the like. One of the most important and challenging tasks in these applications is video compression. The task of video compression is complex and limited by two conflicting parameters: compression efficiency and computational complexity. Video coding standards such as ITU-T H.264 / AVC or ITU-T H.265 / HEVC provide a good compromise of parameters. For this reason, support for video coding standards is almost a mandatory req...
