Paper Abstract

A focus of attention mechanism for locating blob- and edge-like visual steel surfe defects, is proposed in the paper. An inherent problem with focus of attention mechanisms is that weak events arc masked by strong events and pass unnoticed. Solutions to this problem, based on model driven purposive vision, arc discussed. Results obtained with the attention mechanism are illustrated with sample fect images of stretcher streams, roll marks and rust spots.
