چکیده
2 Department of Applied Mathematics, Chhatrapati Shivaji Institute of Technology, Durg (C.G.), (India) ABSTRACT Image compression is a process of reducing or eliminating all redundant or irrelevant data. The new compression technique called Fractal image compression. This scheme works by partitioning an image into blocks and using contractive mapping to map each range blocks to its matched domains. In present study we review the work on encoding and decoding to compress the image by fractal image compression with IFS.

MEDICAL IMAGE COMPRESSION: A REVIEW
Within recent years the use of medical images for diagnosis purposes has become necessity. The limitation in transmission and storage space also growing size of medical images has necessitated the need for efficient method, then image Compression is required as an efficient way to reduces irrelevant and redundancy of the image data in order to be able to store or transmits data. It also reduces...
متن کاملComplexity Reduction Methods for FractalImage
Fractal image compression allows fast decoding but suuers from long encoding times. During the encoding a large number of sequential searches through a list of domains (portions of the image) are carried out while trying to nd a best match for another image portion called range. In this article we review and extend the methods that have been developed to reduce the time complexity of this searc...
