Embodiment Construction

[0016] First, it should be understood that although one or more exemplary embodiments are provided below, the system and / or method disclosed in the present invention can be implemented by a variety of currently known or existing technologies. The present invention should never be limited to the illustrative embodiments, drawings, and techniques described below, including the exemplary designs and embodiments described and described herein, but may be within the scope of the appended claims and their equivalents Modify within the full scope of the object.

[0017] Video media usually involves displaying a series of still images or frames in succession relatively quickly, allowing the viewer to feel movement. Each frame can contain multiple image elements or pixels, and each image element or pixel can represent a single reference point in the frame. During digital processing, each pixel may be assigned an integer value (for example, 0, 1, ... or 255), which represents the image qu...

Abstract

An apparatus comprising a processor configured to determine whether to apply an intra smoothing filter for a prediction unit (PU) based on a lookup table (LUT), wherein the LUT comprises data indicating the intra smoothing filter should not be applied for any PU with a block size of 8×8 pixels and associated with directional prediction mode. The disclosure also includes a method comprising generating reference samples, determining a size of a PU block, and selecting the reference samples based on PU block size, wherein filtered reference samples are not selected for PU blocks with a size of 8×8 pixels and associated with directional prediction mode.

Description

[0001] Cross-application of related applications [0002] The present invention requires the United States Provisional Patent Application No. 61 / 588355 filed by Guichun Li et al. on January 19, 2012, entitled "Simplification of Mode Dependent Intra Smoothing" Priority of the earlier application, the content of the earlier application is incorporated into this text by way of introduction, as if the full text is reproduced. [0003] Statement regarding research or development sponsored by the federal government [0004] Not applicable. [0005] References to microfiche attachments [0006] Not applicable. Background technique [0007] Even when the movie is relatively short, a large amount of video data needs to be described. This may cause difficulties when the data is to be streamed or transmitted in other ways in a communication network with limited bandwidth capacity. Therefore, video data is usually compressed and then transmitted in modern telecommunication networks. Video compres...
