One way to perform edge detection in Matlab is by using the Sobel operator. The following code shows an example of using the Sobel operator to detect edges in an image:
main.m317 chars16 lines
In this code, we first load an image and convert it to grayscale. Then we define the Sobel operator kernels dx
and dy
and apply them to the image using the imfilter
function. We compute the gradient magnitude by taking the square root of the sum of squared x and y gradients. Finally, we display the result using the imshow
function.
