Edge Detection Using the Sobel Compass Operator
نویسنده
چکیده
This paper presents edge detection using the Sobel compass edge detector where four processing elements are arranged in parallel to get the edge detected values in different directions of compass to get a accurate edge detected image. The edge detection is done in four stages which include buffer memory, four processing elements, maximum gradient unit and edge map which is designed in verilog and simulated using the MATLAB and Modelsim. This paper also shows edge detected images for different threshold values to know which threshold value will give best edge detected image.

متن کاملNoisy images edge detection: Ant colony optimization algorithm
The edges of an image define the image boundary. When the image is noisy, it does not become easy to identify the edges. Therefore, a method requests to be developed that can identify edges clearly in a noisy image. Many methods have been proposed earlier using filters, transforms and wavelets with Ant colony optimization (ACO) that detect edges. We here used ACO for edge detection of noisy ima...

متن کاملA fast subpixel edge detection method using Sobel-Zernike moments operator
In this paper, a new edge detection approach combining Zernike moments operator with Sobel operator is proposed. This detection consists of two steps: Firstly, all probable edge points are detected using Sobel operator; Secondly, Zernike moments operator is used to relocate the edge precisely from the points detected by Sobel operator. In the second step, two masks (one real and one complex) ar...
