Find edges using the Canny method. BW1 = edge(I,'Canny'); Find edges using the Prewitt method. BW2 = edge(I,'Prewitt'); Display both results side-by-side. imshowpair(BW1,BW2,'montage') Input Arguments collapse
To find edges, you can use theedgefunction. This function looks for places in the image where the intensity changes rapidly, using one of these two criteria: Places where the first derivative of the intensity is larger in magnitude than some threshold ...
The script covers image selection, display, and the application of the Sobel edge detection filter for enhanced visualization of edges in images. The interactive bonus section allows users to select images for processing, providing an engaging hands-on experience. Explore the code to gain...
avgH = integralKernel([1 1 7 7], 1/49); J = integralFilter(intImage, avgH); Cast the result back to the same class as the input image. J = uint8(J); figure imshow(J); Construct Haar-like wavelet filters to find vertical and horizontal edges in an image. ...
