In this paper, we propose an edge detection method for detecting edges by combining a traditional edge detection operator with shear transform utilizing the fact that the shearing operation provides a more favorable treatment of directions. The shearing operation makes the directional edges easy to be detected by traditional operators. Moreover, we can consider the proposed method as a general method...
Different methods for boundary extraction of carotid artery have been proposed in recent years and different research groups have reported contradictory results. The goal of this paper is to present an independent comparative analysis of different boundary extraction techniques (Canny, wavelet with watershed and wavelet with fuzzy C). The techniques are tested with B-mode Ultrasound (US) images of...
Edges are basic low level primitives for image processing. Edge detection is one of the most common operations in image analysis. In this paper a new implementation for edge detection methods using LVQ neural network is proposed. For instance Susan and Canny and Sobel edge detectors are modeled by neural network and simulation results are very promising.
