An Approach for Target Detection and Extraction Based on Biological Vision

Abstract

Abstract Inspired by the mechanism of multi-scale image fusion of insect compound eye, this paper proposed a target detection and extraction method based on insect compound eye and human visual attention mechanism. The main feature of this method is that multi-scale visual attention mechanism is designed for improving the detection accuracy of interested target, meanwhile image is pre-segment based on it, then the target is extracted based on the LEGION (Locally Excitatory Globally Inhibitory Oscillator Networks) selection network model. For multi-scale visual attention mechanism, on intensity channel, this approach adopts multi-scale analysis to get the intensity saliency map on both global-level and local-level; on orientation channel, according to the mechanism of the large vision field of compound eye, directional information is added to improve the orientation sensitivity; on color channel, according to the characteristic of color sensitivity of human vision system, HSI color space is used instead of...
