Wavelet Sub-Band Block Coding Based Lossless High Speed Compression of Compound Image
نویسنده
چکیده
Digital Image Processing is the use of computer algorithms to perform image processing on digital images. Digital image processing has many advantages over analog image processing. It allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and signal distortion during processing. Since images are defined over two dimensions, digital image processing may be modelled in the form of multidimensional systems. It allows the use of much more complex algorithms for image processing and can offer both more sophisticated performance at simple tasks, and the implementation of methods which would be impossible by analog means.

Embedded to Lossless Image Coding (elic)
In this paper, a novel approach for Embedded to Lossless Image Coding (ELIC) is presented. With embedded to lossless coding, lossy encodings of the image at all lower bit rates are embedded in the lossless bit stream. This algorithm uses wavelet transforms that map integers to integers with embedded coding. The coding is based on bit significance criteria in which coefficients that become signi...

متن کاملZerotree Coding of DCT Coefficients
We show that an efficient quantizer originally developed for wavelet compression can be applied to DCT coding with excellent results. We have implemented a system for block-based, embedded, progressive, DCT image compression which makes use of the embedded zerotree wavelet (EZW) algorithm of Shapiro. The image is partitioned into a number of distinct square blocks and the DCT applied to each of...
متن کاملTROBIC: two-row buffer image compression
We describe a color image compression and decompression scheme suitable for high resolution printers. The proposed scheme requires only two image rows in memory at any time, and hence is suitable for low-cost, high-resolution printing systems. The compression ratio can be specified and is achieved exactly. Compound document images consisting of continuoustone, natural regions mixed with synthet...
