In this paper, we propose a new edge detection method that combines the concepts of Logarithmic Image Processing (LIP) and gray level ratio operations. The presented method provides a new approach in edge detection where edges are detected at different ratios of gray levels independently. The proposed method detects edge details based on the band of gray levels ratio of interest that these details lie within, while current edge detection algorithms control such edge details by threshold variations. In the proposed algorithm, variations of some introduced constant value introduce different edge details and not necessarily more or less details. Extensive simulations demonstrate that this method produces competitive results by suppressing impulsive noise, the ability to trace the development of certain object structures, and segmenting objects that belong to a certain area of interest.
