Title:

Animals with Anatomy

Abstract:

Animals are beautiful and lovely. Many people want to see them in computer-generated images and animations. I will present a paper about modeling animals in a realistic way. The author of this paper applies anatomical and physiological to model and animate animals.

• Low Complexity Fractal Image and Video Compression

Work on Fractal Image Compression at Bath has focussed on methods involving low complexity. While others concentrate on reducing the complexity of searching to find block matching, we have demonstrated successful fractal image compression in which searching is entirely eliminated. The Bath Fractal Transform (BFT) relies on a superior basis approximation to improve the rate/distortion performance of an image coder. Its most recent embodiment uses a truncated DCT basis in combination with a frac- tal term which maps an orthogonalized parent block onto a concen- tric child block. Recently we have developed the Implicit Fractal Transform (IFT) whereby the parent can occupy any position relative to the child as long as the child is entirely covered by the parent. The po- sition of the parent can be deduced entirely from the truncated DCT basis, so the fractal term is "free", i.e. no stored (or transmitted) code is required to specify its offset. The IFT method can also be used to apply fractal terms to the decoded results from other image compression methods, e.g. JPEG, and has merit as a post-filter. Also the IFT can be used to zoom images with good results. The extension of low complexity stills to low complexity video requires achieving reasonable fidelity without the costly process of motion prediction. (The latter accounts for as much as 95% of the complexity of compression in the current MPEG-II video compression standard.) Impossible? No more so than doing frac- tals without searching! After various stages of development, our latest adaptive software video compressor consists of a two-layer object based codec with high fidelity background and embedded foreground. It achieves a PSNR 10dB better than "Motion JPEG" and is suitable for a range of applications with fixed cameras such as videoconferencing and surveillance. Some demonstrations of the video compressor will be given.
