Learning Texture Similarity With Perceptual Pairwise Distance, Yan Gao, Lei Wang, Kap Luk Chan, Wei-Yan Yau
Faculty of Engineering and Information Sciences - Papers: Part A
In this paper, we demonstrate how texture classification and retrieval could benefit from learning perceptual pairwise distance of different texture classes. Textures as represented by certain image features may not be correctly compared in a way that is consistent with human perception. Learning similarity helps to alleviate this perceptual inconsistency. For textures, psychological experiments were shown to be able to construct perceptual pairwise distance matrix. We are going to show how this distance information could be utilized in learning similarity by Support Vector Machines for efficient texture classification and retrieval.

A Post-Compilation Register Re-Assignment Technique For Improving Hamming Distance Based Code Compression, Montserrat Ros, Peter Sutton
Faculty of Engineering and Information Sciences - Papers: Part A
Code compression is a field where compression ratios between compiler-generated code and subsequent compressed code are highly dependent on decisions made at compile time. Most optimizations employed by compilers tend to focus on parameters such as program performance, minimizing resource dependencies and sometimes the option of reducing code size. This paper describes a post-compilation technique for the greedy reassignment of general purpose scratch registers to improve Hamming distance based code compression. The code translation renumbers registers based on the frequency of registers used by isomorphic instructions and employs a Gray coding scheme to reduce Hamming distances between similar instructions.
