Lossless 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 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 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 Image Compression Using Data Folding Followed By Arithmetic Coding
The paper presents a lossless image compression technique using the hybridization of two different entropy coding techniques. Initially data folding technique has been applied to the image. A row folding is applied on the image matrix followed by a column folding. Multiple iterations of this process is applied on the image. After completing the data folding process another entropy coding techni...
