A Design of Efficient Scan Converter for Image Compression CODEC

Design of an improved lossless halftone image compression codec

The popularity of high-resolution digital printers and the growing computational requirements of new applications such as printing-on-demand and personalized printing have increased the need for fast and efficient lossless halftone image compression. In a previous paper, we have shown that the compression performance can be improved significantly by adapting the context template to the halftone...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Design of a CCD focal-plane codec preprocessor for lossless image compression

The design of a CCD-based codec preprocessor integrated with an areal imager is presented. The imager is a 256x256 buried channel frame transfer device with 15x15 um2pixels. Conventionally, imagers deliver pixel data in a raster-scan sequential format. Typical of many image processing tasks, the image coding scheme used in our lossless compression algorithm requires 3x3 pixel neighborhood block...

A Just-Noticeable-Distortion Based Perceptually Lossless Image Compression Codec

MEDICAL IMAGE COMPRESSION: A REVIEW

Within recent years the use of medical images for diagnosis purposes has become necessity. The limitation in transmission and storage space also growing size of medical images has necessitated the need for efficient method, then image Compression is required as an efficient way to reduces irrelevant and redundancy of the image data in order to be able to store or transmits data. It also reduces...
