Comparison and Enhancement of Digital Image by Using Canny Filter and Sobel Filter
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 1
Abstract
In this research paper we have defining two different edge detection methods i.e canny edge detection and Sobel edge detection and we are also discussing some image quality parameters like PSNR, SNR, MSE, RMSE, UQI and MAE. Edge detection is a technique that is used to identifying points in a digital image at which the image brightness changes sharply or, more formally, has discontinuities. The points at which image brightness changes sharply are typically organized into a set of curved line segments termed edges. Results shows that our strategy on the nature of comparison between canny and sobel edge detection methods by using image quality parameters on Medical images [ MRI and CT Scan] and to further finding a better and more accurate edge detection method .The values of these methods are interpreted and illustrated in results section .
