Fractal compression and scanned images

Abstract

The digitisation of images produces large data files. A scanned A4 size line drawing might typically occupy 80Kb, a 5 inch by 4 inch black and white photograph 400Kb and the colour equivalent 4Mb. Describes technology for compressing image files with the example of Wirral Metropolitan college's 112 black and white photographs with text and display software compressed onto a 1.44Mb diskette. This was achieved by fractal image compressioin which may operate up to ratios of 100:1. Explains the advantages of Dr. Michael Barnsley's Fractal Transform. It is particularly effective for complex, high resolution images of nature
