Performance Evaluation of Various Thresholding Methods using Canny Edge Detector

Performance Analysis of Adaptive Canny Edge Detector Using Bilateral Filter

Canny operator has proved as an optimal edge detector due to due to good localization, detection and only one response to single response. However it has some drawbacks. An improved algorithm has proposed by Gao Lie in which bilateral filtering is used that have better edge preserving and noise removing capabilities. For achieving adaptive thresholding OTSU‟s method is used which automatically ...

Semantic Image Segmentation using Canny-Edge Detector

Semantic Image Segmentation (SIM) is one of the most important areas of image processing. It is used in different fields like robotics, satellite imaging, Biometric verification etc. Image segmentation system depends mainly on two processes, i.e. image feature extraction and object class learning. Some of the researchers have exploited image feature like Texton-Feature, by the help of Texton fe...

On the Canny edge detector

The Canny edge detector is widely used in computer vision to locate sharp intensity changes and to nd object boundaries in an image The Canny edge detector classi es a pixel as an edge if the gradient magnitude of the pixel is larger than those of pixels at both its sides in the direction of maximum intensity change In this paper we will show that de ning edges in this manner causes some obviou...

Balancing High-Performance Parallelization and Accuracy in Canny Edge Detector

We present a novel approach to tradeoff accuracy against the degree of parallelization for the Canny edge detector, a well-known image-processing algorithm. At the heart of our method is a single toplevel image-slicing loop incorporated into the sequential algorithm to process image segments concurrently, a parallelization technique allowing for breaks in the computational continuity in order t...
