Lossless-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 Survey on Lossless and Lossy Data Compression Methods
Compression is built into a broad range of technologies like storage systems, databases, operating systems and software applications. It refers to the process of reducing the quantity of data used to represent the content without excessively reducing the quality of the original data. Their main purpose is to reduce the number of bits required to store and/or transmit digital media in a cost eff...
متن کاملLossless and Lossy Data Compression
Data compression (or source coding) is the process of creating binary representations of data which require less storage space than the original data 7; 14; 15]. Lossless compression is used where perfect reproduction is required while lossy compression is used where perfect reproduction is not possible or requires too many bits. Achieving optimal compression with respect to resource constraint...
متن کاملA Review on Lossless Image Compression Techniques
Compression is a technique to reduce the quantity of data without excessively reducing the quality of the data. Image compression is the application of data compression on digital images. Image compression is used to minimize the amount of memory needed to represent an image, for storage or transmission of information. When hearing that image data are reduced, one could expect that automaticall...
