Abstract

In this paper, we introduce a human visual system (HVS)-based edge detection algorithm. The introduced algorithm integrates image enhancement, edge detection and logarithmic ratio filtering algorithms to develop an effective edge detection method. Also a parameter (â) is introduced to control the level of detected edge details and functions as a primary threshold parameter. The introduced algorithm functions in tracking and segmenting significant dark gray levels in an image. Simulation results have shown the effectiveness of the introduced algorithm compared to other traditional methods such as Canny's algorithm in preserving object's topology and shape. The developed algorithm functions at various applications where measurements and segmentation of dark gray level spots for classification and tracking purposes are required such as road cracks, lunar surface images, and remote objects.
