چکیده
1 FAST NOISE SUPPRESSION FOR LOSSLESS IMAGE CODING (EXTENDED PREPRINT) Tilo Strutz University of Rostock, Institute of Communications and Information Electronics Richard-Wagner-Str.31, 18119 Rostock, FRG ABSTRACT: This contribution presents a new denoising method for applications requiring preservation of highest visual image quality. The aim of the new approach is not to suppress all noise inside images, but to remove as much as possible without visible changes. This property holds even if the denoised image will be processed further, e.g. in terms of moderate contrast enhancement. As one important result, reversible (lossless) coding schemes can obtain substantial higher compression rates than without noise suppression.

Simple Lossless and Near-lossless Waveform Compression
This report describes a program that performs compression of waveform les such as audio data. A simple predictive model of the waveform is used followed by Huuman coding of the prediction residuals. This is both fast and near optimal for many commonly occuring waveform signals. This framework is then extended to lossy coding under the conditions of maximising the segmental signal to noise ratio...
متن کاملInteger fast lapped transforms based on direct-lifting of DCTs for lossy-to-lossless image coding
The discrete cosine transforms (DCTs) have found wide applications in image/video compression (image coding). DCT-based lapped transforms (LTs), called fast LTs (FLTs), overcome blocking artifacts generated at low bit rate image coding by DCT while keeping fast implementation. This paper presents a realization of more effective integer FLT (IntFLT) for lossy-to-lossless image coding, which is u...
متن کاملLossless image compression using binary wavelet transform
A binary wavelet transform (BWT) has several distinct advantages over a real wavelet transform when applied to binary data. No quantisation distortion is introduced and the transform is completely invertible. Since all the operations involved are modulo-2 arithmetic, it is extremely fast. The outstanding qualities of the BWT make it suitable for binary image-processing applications. The BWT, or...
متن کاملA two-layered wavelet-based algorithm for efficient lossless and lossy image compression
In this paper, we propose a wavelet-based image-coding scheme allowing lossless and lossy compression, simultaneously. Our two-layered approach utilizes the best of two worlds: it uses a highly performing wavelet-based or wavelet packet-based coding technique for lossy compression in the low bit range as a first stage. For the second (optional) stage, we extend the concept of reversible integer...
متن کاملFast Lossless Compression of Medical Images based on Polynomial
In this paper, a fast lossless image compression method is introduced for compressing medical images, it is based on splitting the image blocks according to its nature along with using the polynomial approximation to decompose image signal followed by applying run length coding on the residue part of the image, which represents the error caused by applying polynomial approximation. Then, Huffma...
