Fractal image compression (FIC) is a lossy compression method. In fractal image compression an image is coded as a set of contractive transformations in a complete metric space. ... For all modalities of images the compression ratio and Peak Signal to Noise Ratio (PSNR) are computed and studied. The quality of the decompressed image is arrived by PSNR values. ... Hence in this work, T max =8 is found to be the optimum value for medical images using Fractal image compression. ...doi:10.5281/zenodo.1330356 fatcat:n6i6xsxlszemxpzodb5nqqtsg4
Fractal image compression is a recent technique based on the representation of an image by a contractive transform, on the space of images, for which the fixed point is close approximation to the original ... Fractal image compression is a lossy compression method for digital images, based on fractals. ... For a large fractal image compression time can be measured in hours, rather than seconds or even minutes for large images. ...doi:10.5120/14830-3081 fatcat:djorp4rfwvgrpovd5lh3yd6fba
Direct Cosine Transform (DCT) and Fractal Image Compression (FIC) are types of lossy compression methods. ... This work shows that lossy compression methods can be chosen for medical image compression without significant degradation of the image quality. ... A fully automatic Fractal based image compression technique of digital monochrome images was first proposed by Jacquin  .The encoding process of an image is given by approximating the smaller range ...doi:10.5281/zenodo.1080796 fatcat:amrwpmqf35acpomapj6yu4nkva

Our experimental results show that BSP tree representation is effective in reducing total energy for secure transmission for computer arts images compared to JPEG. ... Our experimental result shows that in most cases, our new tree construction and compression formula use only 40% of the original total energy required for compressing and sending images. ... Finally, our image representation allows users to choose different pruning thresholds for different areas of the image. ...doi:10.1007/11422778_11 fatcat:ohvdj3jwwzhrrkvsfyt3plj3ay
This is the case with the free compresssion and die compaction tests. ... Determination of the fractal dimension from images using a grid shows that the fractal dimension varles with the number of subdivisions of the grid. ... The application of the concept of fractal sealing for the characterization of images and pore size distributions follows in chapter 5. ...doi:10.6100/ir415055 fatcat:3pjnedxwkjaexgfghya2yhqvke
