Intra Block Copy in HEVC Screen Content Coding Extensions
Publication Year: 2016, Page(s):409 - 419
Cited by: Papers (3)With the emerging applications such as online gaming and Wi-Fi display, screen content video, including computer generated text, graphics and animations, becomes more popular than ever. Traditional video coding technologies typically were developed based on models that fit into natural, camera-captured video. The distinct characteristics exhibited between these two types of contents necessitate th... View full abstract»

Palette Mode Coding in HEVC Screen Content Coding Extension
Publication Year: 2016, Page(s):420 - 432
Cited by: Papers (2)Palette mode is a new coding tool included in the HEVC screen content coding extension (SCC) to improve the coding efficiency for screen contents such as computer generated video with substantial amount of text and graphics. It is observed that a local area in screen content typically has a few colors separated by sharp edges. To exploit such characteristics, palette mode represents samples in a b... View full abstract»

Improvements of HEVC SCC Palette Mode and Intra Block Copy
Publication Year: 2016, Page(s):433 - 445Palette mode and intra block copy are two new coding tools that have been adopted in the screen content coding extensions of high efficiency video Ccoding (HEVC SCC). Palette mode can represent color clusters for screen content efficiently. Intra block copy (IBC) facilitates block prediction within the same frame. Both tools have demonstrated promising benefits for screen content coding. In additi... View full abstract»

Adaptive Color-Space Transform in HEVC Screen Content Coding
Publication Year: 2016, Page(s):446 - 459
Cited by: Papers (1)The screen content coding (SCC) Extensions of high efficiency video coding (HEVC) employs in-loop adaptive color-space transform (ACT) technique to explore the inter-color-component redundancy, i.e., statistical redundancy among different color components. In ACT, the prediction residual signal is adaptively converted into a different color space, i.e., YCgCo. The rate-distortion criteria is emplo... View full abstract»

VESA Display Stream Compression for Television and Cinema Applications
Publication Year: 2016, Page(s):460 - 470
Cited by: Papers (1)The Video Electronics Standards Association (VESA) Display Stream Compression (DSC) standard is widely accepted as a low-cost, visually lossless codec for use in display links. However, as high dynamic range (HDR) and wide color gamut (WCG) technologies become more prevalent, several new features are needed to address television and cinema applications, including support for greater bit depths and...

Quality and Error Robustness Assessment of Low-Latency Lightweight Intra-Frame Codecs for Screen Content Compression
Publication Year: 2016, Page(s):471 - 483Today, many existing types of video transmission and storage infrastructure are not able to handle UHD uncompressed video in real time. To reduce the required bit rates, a low-latency lightweight compression scheme is needed. To this end, several standardization efforts, such as Display Stream Compression, Advanced DSC, and JPEG XS, are currently being made. Focusing on screen content use cases, t... View full abstract»

Fixed-Ratio Compression of an RGBW Image and Its Hardware Implementation
Publication Year: 2016, Page(s):484 - 496
Cited by: Papers (1)In the latest large-screen TVs, an RGBW color domain is widely used to enhance the brightness of liquid crystal display (LCD) panels. As the correlations among RGBW color components are different from those among conventional RGB components, a compression algorithm developed for an RGB image may not be efficient for RGBW compression. For high-fidelity RGBW image coding, a novel prediction-based co... View full abstract»

DPCM-Based Edge Prediction for Lossless Screen Content Coding in HEVC
Publication Year: 2016, Page(s):497 - 507Screen content sequences are ubiquitous type of video data in numerous multimedia applications like video conferencing, remote education, and cloud gaming. These sequences are characterized for depicting a mix of computer generated graphics, text, and camera-captured material. Such a mix poses several challenges, as the content usually depicts multiple strong discontinuities, which are hard to enc... View full abstract»

Lossless Intra Compression of Screen Content based on Soft Context Formation
Publication Year: 2016, Page(s):508 - 516The challenge in data compression is to transmit or store a minimum number of bits per sample that should be as close as possible to the number of bits defined by the actual average information content. The latter can be approximated by the contextual entropy. The dilemma is generally that the optimal estimation of contextual symbol probabilities is a kind of artificial-intelligence problem and re... View full abstract»

Subjective and Objective Quality Assessment of Compressed Screen Content Images
Publication Year: 2016, Page(s):532 - 543
Cited by: Papers (3)Objectively accessing the quality of screen content images (SCIs) is a challenging problem, as SCIs may not always have identical properties as natural scenes. Here we conduct comprehensive studies on the subjective and objective quality assessment of the compressed SCIs. Firstly, we build a database that contains the distorted SCIs generated by the high efficiency video coding standard as well as... View full abstract»

A Hardware Decoder Architecture for General String Matching Technique
Publication Year: 2016, Page(s):560 - 572This paper proposes a low cost hardware decoder design and architecture that supports general string matching (SM) using both a primary reference buffer (PRB) and a secondary reference buffer (SRB). An SM decoding module mainly performs string copy operation. The SM decoding module can also support intra block copy and palette decoding because both are actually two special cases of general string ... View full abstract»

Screen Content Image Segmentation Using Robust Regression and Sparse Decomposition
Publication Year: 2016, Page(s):573 - 584
Cited by: Papers (8)This paper considers how to separate text and/or graphics from smooth background in screen content and mixed document images and proposes two approaches to perform this segmentation task. The proposed methods make use of the fact that the background in each block is usually smoothly varying and can be modeled well by a linear combination of a few smoothly varying basis functions, while the foregro...
