Abstract

Low level visual information processing and information extraction are important aspects of any machine vision system. The biological retina is a robust visual low level preprocessor for the extraction of information in the visual channel. Extraction of transition and edge information from signals and visual images in the presence of noise is an important class of problems, both in the field of signal and image processing. In this paper we describe a class of discriminant operators for the extraction of transition information from noisy one dimensional signals. The discriminant operator, as briefly introduced in this paper, attempts to emulate the robust information extraction properties of the receptive fields found in the retina and the visual channel leading to the visual cortex. The discriminant operator, (0 operator) has differential properties with inherent aggregation. The differentiation property helps to extract transition and edge information, while the aggregation operation provides noise immunity. This theory will be used in the development of robust algorithms for robotics, medical image processing and vision prosthesis.
