Due to the rapid growth of web conferences, remote screen sharing, and online games,
screen content has become an important type of internet media information and over 90% of …

We present a compound image compression algorithm for real-time applications of
computer screen image transmission. It is called shape primitive extraction and coding …

Color quantization (cq), the reduction of the number of distinct colors in a given image with
minimal distortion, is a common image processing operation with various applications in …

Screen content like cartoons, captures of typical computer screens or video with text overlay
or news ticker is an important category of video, which needs new techniques beyond the …

Compound images are a combination of text, graphics and natural image. They present
strong anisotropic features, especially on the text and graphics parts. These anisotropic …

ABSTRACT A data coder prepares a frame of data for transmission over a data channel. The
frame is? rst broken into a series of non-overlapping blocks. The blocks are analyzed to …

The mixed raster content (MRC) standard (ITU-T T. 44) specifies a framework for document
compression which can dramatically improve the compression/quality tradeoff as compared …

This paper presents a novel block-based segmentation and adaptive coding (BSAC)
algorithm for visually lossless compression of scanned documents that contain not only …

In this paper, we propose a new encoder for scanned compound documents, based upon a
recently introduced coding paradigm called multidimensional multiscale parser (MMP). MMP …

The mixed raster content (MRC) model can be used to implement highly effective document
compression algorithms. MRC document coders are typically based on the use of a binary …
