Title: HYBRID FRACTAL IMAGE COMPRESSION BASED ON RANGE BLOCK SIZE
Authors: Mohammed Ismail. B and T .Bhaskara Reddy and B.Eswara Reddy
Abstract: The present paper proposes Hybrid Fractal image compressions (HFIC) for grey and Color images. The HFIC method is carried out for the variable size range blocks. The sample images here are divided into blocks by considering minimum and max size ranges. This method transforms the RGB color image into three planes and then divide them into variable ranges. To achieve fractal compression, Relative transformation and entropy coding is applied. The image is reconstructed by applying the inverse transforms and iterative functions. The results of the present analysis demonstrate that, for the hybrid fractal compression scheme with variable range method applied to color and gray scale images like Lena, medical MRI etc, show higher CR and PSNR values compared to fixed range block size and other existing methods. The results indicate that both color and gray level images with Rmax = 16 and Rmin = 8 shows higher Compression ratio(CR) and good Peak Signal to Noise Ratios (PSNR).
Keywords: Hybrid fractal image compression (HFIC), Minimum range Block, maximum range Block, Relative transformation and entropy
