The Canny edge detection operator was developed by John F. Canny in 1986 and uses a multi-stage algorithm to detect a wide range of edges in images. Most importantly, Canny also produced a computational theory of edge detection explaining why the technique

The Canny operator was designed to be an optimal edge detector (according to particular criteria---there are other detectors around that also claim to be optimal with respect to slightly different criteria). It takes as input a gray scale image, and produces as output an image

The Canny edge detector is widely used in computer vision to locate sharp intensity changes and to find object boundaries in an image. The Canny edge detector classifies a pixel as an edge if the gradient magnitude of the pixel is larger than those of pixels at both 

Using the Canny edge detector for feature extraction and enhancement of remote sensing images

ABSTRACT Edges are important features in an image since they represent significant local intensity changes. They provide important clues to separate regions within an object or to identify changes in illumination. Most remote sensing applications, such as image 

The accuracy of sub-pixel localisation in the canny edge detector

ABSTRACT We examine the accuracy of the sub-pixel location of edges in the Canny detector using a discrete step edge model and Monte-Carlo simulation. Comparison is made with previously published analysis in the continuous domain. In this paper we identify potential 

Fast adaptive threshold for the canny edge detector

The Canny edge detector is widely used in computer vision to locate sharp intensity changes and find object boundaries in an image. The Canny edge detector removes the weak edges by hysteresis threshold and has difficulty to find upper and low thresholds 

Performance evaluation of ISEF and Canny edge detector in Acrylic fiber quality control production

ABSTRACT Edge detection algorithms play a vital role in any machine vision system's performance. Two optimal edge detection algorithms are predominating one in image processing: Canny Edge Detection and ISEF also known as Shen Castan algorithm. In 

Chin contour estimation using modified Canny edge detector

ABSTRACT A novel method to estimate the chin contour which is the curve that separates the chin region from the neck region of a human face is proposed. The method assumes that the face and neck region has been separated from the background and the locations of eyes, 

A distributed psycho-visually motivated Canny edge detector

ABSTRACT This paper proposes a distributed Canny edge detection algorithm which can be mapped onto multi-core architectures for high throughput applications. In contrast to the conventional Canny edge detection algorithm which makes use of the global image
