Screen content images are originally captured in a full-chroma format. The chroma
downsampling, which is commonly applied to the chroma component in screen content …

In this paper, we propose an effective novel content-aware chroma reconstruction (CACR)
method for screen content images (SCIs). After receiving the decoded downsampled YUV …

In this paper, we propose a novel adaptive chroma subsampling-binding and luma-guided
(ASBLG) chroma reconstruction method for screen content images (SCIs). After receiving the …

In professional markets, there is a growing need to incorporate off-the-shelf consumer-level
hardware to reduce costs and speed up development. Typically, these hardware …

In color image compression, the chroma components are often sub-sampled before
compression and up-sampled after compression. Although sub-sampling the chroma …

This paper introduces a practical inter-color up-sampling algorithm for images with
decimated chrominance components. Most of the existing and emerging image and video …

Computer screens contain discontinuous-tone content and continuous-tone content. Thus,
the most effective way for screen content coding (SCC) is to use two essentially different …

In this paper, we propose a novel and effective hybrid method, which joins the conventional
chroma subsampling and the distortion-minimization-based luma modification together, to …

We present a direct image resizing method in the compressed domain. Our method reduces
the ringing effect for blocks with vertical or horizontal edge. Moreover, our method omits the …

We propose a novel just noticeable difference (JND) model for a screen content image
(SCI). The distinct properties of the SCI result in different behaviors of the human visual …
