Illusory Contours formed by LED Arrays
This research centred around explaining why the text on LED Arrays appears to be tilted. When text is scrolling on an LED Array the text appears to be orientated approx. 10 degrees off vertical. The project investigated the physiology and psychology of visual perception, and attempted to explain the illusion in those terms.
Automated Inspection of Shadow Masks
This research was done in conjunction with LG Electronics, the objective of which was to detect defects in CRT shadow masks using physiological models of human perception. The main steps involved in this research were first to propose a physiological model which explained why human operators can detect tiny defects in shadow masks, then to construct an inspection system and develop software to simulate the physiological processes.
