This Chapter describes the main edge detection methods based on the gradient technique; such as the Morphological gradient and Sobel operator. We present some concepts, equations and pseudocode to apply these methods on grayscale and color images. We also describe in this chapter some filters used in digital image processing in wh...
Edges can be defined as boundary between two different regions in an image. Edge detection refers to the process of identifying and locating sharp discontinuities in an image. Edge detection process significantly reduces the amount of data and filters out useless information, while preserving the ...

In this paper we will introduce a new class of median type filters to be used in image processing. Two specific applications will be discussed: filters for edge detection and filters for noise reduction without blurring the edges and without losing fine details of the image. The filters are ...

A number of edge detection methods employ 2D Gabor filters. These filters are characterized by frequency, width and direction and have been mainly applied to object recognition problems. [5] introduced an edge detection scheme using Gabor filters, and derived optimal design parameters for detection ...
