The State of the Art in Image Compression

Abstract: In today�s digital world information exchange is been held electronically. This transmission should provide efficiency in factors like transfer speed, cost, transmission errors etc. Image compression is minimizing the size in bytes of an image without reducing the quality of the image to an unacceptable level. It makes the transmission process faster, provides larger bandwidth and security against illicit use of data. This paper addresses the area of image compression as it is applicable to various fields of image processing. So Image compression is used to provide efficient transfer of data. This paper provides a basic introduction about image compression, and various types of image compression techniques.
