Comparison of Colour Spaces for Optic Disc Localisation in Retinal Images
The location of the optic disc is of critical importance in retinal image analysis. In this work we improve on an approach introduced in [3] who localised an optic disc region thr...

Natural Image Correction by Iterative Projections to Eigenspace Constructed in Normalized Image Space
Image correction is discussed for realizing both effective object recognition and realistiic image-based rendering. Three image normalizations are compared in relation with the li...

Analysis of Symbol Error Rates for Signal Space Diversity in Rayleigh Fading Channels
— A signal space diversity (SSD) scheme is one of techniques to achieve diversity gain in fading channels. This method consists of two key operations: constellation rotation and ...
