A Survey on Lossless and Lossy Data Compression Methods
نویسنده
چکیده
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 effective manner. There are number of data compression techniques used and they can be categorized as Lossless and Lossy compression methods. In this paper, we made an attempted to discuss about some of the general concepts of compression algorithm using Lossless and Lossy methods of compression.

Compression can be done by lossy or lossless methods. The lossy methods have been used more widely than the lossless compression. Although, many methods for image compression have been proposed yet, the methods using intelligent skipping proper to the visual models has not been considered in the literature. Image inpainting refers to the application of sophisticated algorithms to replace lost o...
متن کاملA Survey on Methods and Systems for Graph Compression
We present an informal survey (meant to accompany another paper) on graph compression methods. We focus on lossless methods, briefly list available approaches, and compare them where possible or give some indicators on their compression ratios. We also mention some relevant results from the field of lossy compression and algorithms specialized for the use on large graphs. — Note: The comparison...
متن کاملA Survey of Various Data Compression Techniques
This paper is a survey of various methods of data compression. When the computer age came about in the 1940’s, storage space became an issue. Data compression was the answer to that problem. The compression process takes an original data set and reduces its size by taking out unnecessary data. There are two main types of compression, lossy and lossless. This paper will deal exclusively with los...
متن کاملA Survey on Various Image Compression Techniques
Image compression technique is widely used in multimedia applications such as image, video, audio data and medical field. Image compression aims to reduce the redundancy of an image data and reduce the storage space of an image. Different image compression techniques were proposed to achieve high compression ratios and high image qualities in low computation time. This document presents the rev...
متن کاملA Survey of Image Compression Methods
The research in the field of image compression is driven by the ever increasing bandwidth requirements for transmission of images in computer, mobile and internet environments. In this context, the survey summarizes the major image compression methods spanning across lossy and lossless image compression techniques and explains how the JPEG and JPEG2000 image compression techniques are distinct ...
