Fractal image compression is used in computer science, based on the facts of fractal geometry. By using this technique image is much more compressed as compared to JPEG, GIF, etc. Also, there is no pixelization when the picture is enlarged. To ease the study of turbulent flows, fractal representation is used. Compression of images by the JPEG algorithm should be limited to those intended strictly for visual display, such as presentation in Web pages or distributed in portable document format (PDF). Digital images captured in the microscope that are destined for serious scientific scrutiny with regard to dimensions, positions, intensities, or colors of features should never be subjected to lossy compression before analysis.

Image Compression using Huffman Coding Huffman coding is one of the basic compression methods, that have proven useful in image and video compression standards.
