convolution with sobel in matlab

To perform convolution with Sobel in MATLAB, follow these steps:

1. Load the image in MATLAB using the imread function
2. Convert the image to grayscale using the rgb2gray function
3. Define the Sobel operator using the fspecial function
4. Convolve the image with the Sobel operator using the imfilter function
5. Display the result using the imshow function

Here's the code:

main.m
% Load the image
image = imread('image.jpg');

% Convert the image to grayscale
gray_image = rgb2gray(image);

% Define the Sobel operator
sobel_operator = fspecial('sobel');

% Convolve the image with the Sobel operator
convolved_image = imfilter(gray_image, sobel_operator);

% Display the result
imshow(convolved_image);

This code will produce an edge-detected image of the original image using Sobel operator.
