COMPARISON ANALYSIS OF SENSITIVITY OF NOISE B/W VARIOUS EDGE DETECTION TECHNIQUE BY ESTIMATING THEIR PSNR VALUE

Edge (corner) are boundaries (borders) between different textures. Edge (corner) also may be defined as discontinuities in image (picture) intenseness from one pixel (picture element) to other. Edge (corner) for a image (picture) are always important characteristics that recommend a suggestion for a higher frequency. Edge (corner) detection (identification) is a image (picture) processing technique for finding boundaries (borders) of objects within images (pictures). It works as a result of detecting discontinuation in brightness (clarity). Edge (corner) detection (identification) is used for image (picture) segment & data mining in areas such as image (picture) processing, computer vision, & machine vision. Common edge (corner) detection (identification) algorithms include Sobel, Canny, Prewitt, Roberts & fuzzy logic methods.
