Early warning of floods is an essential part disaster management. Various automatic detectors have been developed in flood mitigation, including cameras. But reliability and accuracy not improved. Besides, the use monitoring devices has employed to monitor water levels various building facilities. The early detector was carried out with a sensor camera using orange ball that floats near level g...

Conventional Canny edge detector can detect edges in image with additive noise effectively but not ultrasound image that are corrupted by multiplicative speckle noise which alleviates image resolution resulting in inaccurate characterization of object features. In this paper, we proposed to incorporate the modified SRAD into the Canny edge detector to replace the Gaussian blurring in the conven...

In this paper the authors present the development of an algorithm based on the Edge Detection Technique for Automatic Detection of Brain Tumors in MR Images of the Brain and their Quantification. The basic Edge detection technique is primarily based on the abrupt changes in the intensities between the tumor and the brain regions, identified through gradient operations. This is implemented throu...

In One of the most essential methods in digital image processing is edge detection. Because its capacity to detect edges even images heavily contaminated by noise, Canny detector widely used detection algorithm. A modified canny created MATLAB and implemented FPGA this project. The mask for gradient calculation, bilinear interpolation four pixels non-maximal suppression. iris subsystem, as a pr...

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...

This paper addresses the problem of implementing an object detection and classification system on a parallel virtual machine. Detection process was implemented using deformable template algorithm. Canny edge algorithm used to provide edge information need in template matching. The system gives descriptions about the shape, size, and orientation of the objects. To be implemented in industrial pr...

In this paper, a novel approach based on edge line segments and texture is presented for urban change detection. First, we extract edge line segments based on Canny edge detector and line-support regions based on gradient orientation, Then changed edge line segments are found and grouped into clusters as potential changed regions which are finally validated using the difference of pixels and te...
