The image compression using fractal transform is a promising method which is potentially capable of achieving very high compression ratios. The major drawback of fractal inage compression is large encoding time, though the decoding time is negligible. In this paper, a new similarity measure based on normalized cross-correlation of mean subtracted range and domain blocks is proposed.The fast fractal encoding algorithm based on the proposed similarity measure is well suited for FFT baseddoi:10.5176/978-981-08-7656-2atai2010-60 fatcat:bqcnek5afzf6jgv6gi4y24lghe
