This paper presents the comparative review of wavelet encoder and fractal image compression (FIC) based on DWT. Wavelet transforms, and FIC are popularly used as the domain for image compression. Encoder designed in the spatial domain cannot exploit the redundancy present in the natural image efficiently. In this paper, the image is encoded using conventional fractal encoding algorithm in both the transforms. Performance of both the encoder compared using compression ratio, encoding time and PSNR. Raw images of size 512×512 used to carry the experiment in Matlab2013a. A quick review is arranged in a tabular manner in Sect. 4.
