Lossless/lossy coding gain to evaluate coding performance of the lossless/lossy wavelet
نویسندگان
چکیده
In this report, we propose lossless/lossy coding gain as a new objective criterion to theoretically evaluate lossless and lossy coding performance of the lossless/lossy wavelet (LLW). The proposed lossless/lossy coding gain consists of three parameters: “lossless coding gain”, “quantization-lossy coding gain” and “rounding errors”. Performances of 15 kinds of the LLW are measured with two-dimensional (2D) octavedecomposition. Some standard images are applied as input signals to evaluate coding performance of the LLW.

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 کاملLossless-by-Lossy Coding for Scalable Lossless Image Compression
This paper presents a method of scalable lossless image compression by means of lossy coding. A progressive decoding capability and a full decoding for the lossless rendition are equipped with the losslessly encoded bit stream. Embedded coding is applied to largeamplitude coefficients in a wavelet transform domain. The other wavelet coefficients are encoded by a context-based entropy coding. Th...
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 کاملFrom Lossy to Lossless Wavelet Image Coding in a Tree-Based Encoder with Resolution Scalability
For a lossy encoder, it is important to be able to provide also lossless compression with little or no modification of the usual algorithm, so that an implementation of that algorithm can work in lossy or lossless mode, depending on the specific application, simply by varying the input parameters. In this paper, we evaluate the capability of the Lower Tree Wavelet (LTW) image encoder to work in...
متن کاملHyperspectral Image Lossy-to-Lossless Compression Using 3D SPEZBC Algorithm Based on KLT and Wavelet Transform
In this paper, we propose a hyperspectral image lossy-tolossless compression using three-dimensional Embedded ZeroBlock Coding (3D EZBC) algorithm based on Karhunen-Loève transform (KLT) and wavelet transform (WT). Furthermore, an improved Hao’s matrix factorization method for integer KLT is also presented, which can reduce not only the computational complexity but also the memory requirements....
