Webthe edge of the image. 1-A Gaussian blur is applied to clear any speckles and free the image of noise. I do the gaussian blur. 2-A gradient operator is applied for obtaining the … The Canny algorithm contains a number of adjustable parameters, which can affect the computation time and effectiveness of the algorithm. • The size of the Gaussian filter: the smoothing filter used in the first stage directly affects the results of the Canny algorithm. Smaller filters cause less blurring, and allow detection of small, sharp lines. A larger filter causes more blurring, smearing out the value of a given pixel over a la…
