| Abstract | ||
| In this paper an algorithm is proposed to reduce the long time that has been taken in the Fractal image compression (FIC) technique. A variance factor is used to reduce the number of matching operations between Range and Domain blocks through exclude the homogenous or flat regions. This in turn reduces the number of complex computations required by the compression’s algorithm by FIC and this will lead to reduce the encoding time required by coding operation. Several gray images (256x256) have been tested (256x256) pixel (partitioned into fixed block size of (4x4)) using visual C++ 6.0 code. Suggested scheme reduces the number of range-domain comparisons with significant amount and gives improved time performance faster about 70% with a higher compression ratio and high-quality images | ||
