Lossless Scalable Coding of Images via Lossless Multi-Channel Prediction∗
نویسندگان
چکیده
A new lossless scalable coding based on a lossless wavelet transform (LWT) and a lossless multi-channel prediction (LMP) is proposed. A rough image can be expanded from a part of the bit stream for the use of progressive transmission. The LMP, a non-separable 2D filter bank, is optimized for an arbitrary input image signal so that remaining correlation of the band signals of the LWT can be utilized. Filter coefficients are optimized for each of input images under the lossless coding gain. key words: lossless, coding, wavelet, JPEG

Lossless/Lossy Progressive Coding Based on Reversible Wavelet and Lossless Multi-Channel Prediction
In this report, a digital image data compression method which has two modes – “losslesss” mode and “lossy” mode – and also “progressive” functionality is proposed. The coding system can be optimized for an arbitrary input image signal under the lossless / lossy unified coding gain introduced here.
متن کاملAn Enhanced Lossless Image Compression Based on Hierarchical Prediction Context Adaptive Coding
To display high bit resolution images on low bit resolution displays, bit resolution needs to be reduced. Towards achieving a reduced bit rates and high compression gain, an enhanced method for compression of various color images are presented, which is based on hierarchical prediction and adaptive coding. An RGB image is first transformed to YCbCr by a reversible color transform and a various ...
متن کاملAdapted generalized lifting schemes for scalable lossless image coding
Still image coding occasionally uses linear predictive coding together with multi-resolution decompositions, as may be found in several papers. Those related approaches do not take into account all the information available at the decoder in the prediction stage. In this paper, we introduce an adapted generalized lifting scheme in which the predictor is built upon two filters, leading to taking...
متن کاملA Design of Lossless Compression for High-Quality Audio Signals
Three extension tools for extending and enhancing the compression performance of prediction-based lossless audio coding are proposed. The first extension aims at supporting floatingpoint data input in addition to integer PCM data. The second is progressive-order prediction of the starting samples at each random-access frame, where the information on previous frame is not available. The third is...
متن کاملMPEG-4 SLS – Lossless and Near-Lossless Audio Coding Based on MPEG-4 AAC
MPEG-4 Scalable Lossless Coding (SLS) is one of the latest extensions to the MPEG-4 audio coding standard. It provides a scalable lossless extension of the well-known MPEG4 AAC codec. The lossless enhancement is performed in a finegrain scalable way, starting from the AAC core signal in small steps all the way up to a numerically lossless representation, thus also including near-lossless compre...
