Implementation of an Orientation Selective Hierarchical Spatial Filter Using Diffusion Network

proposed in 1980 simultaneously by Daugman [9] in two-dimensional form and by Marcelja [lo] in oneThis paper describes a neural network which detects dimensional form. the edges of different orientation and spatial frequency Watson [ l l ] proposed a cortex transform which in an image. The proposed neural network is useful for maps an image into a set of image that vary in image analysis, feature extraction, and texture resolution and orientation. The cortex transform was segmentation. designed to create several pyramids, one per selected orientation. Other band-pass filters with spatial
