find corners of object in image in matlab

To find the corners of an object in an image in Matlab, you can use corner detection algorithms such as Harris corner detection or FAST corner detection. Here is an example of how to use the Harris corner detection algorithm to find the corners of an object in an image:

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

% Convert the image to grayscale
gray_img = rgb2gray(img);

% Apply the Harris corner detector
corners = detectHarrisFeatures(gray_img);

% Display the image with the detected corners
imshow(gray_img); hold on;
plot(corners.selectStrongest(50));

In this example, we first load the image and convert it to grayscale. Then we apply the Harris corner detector using the detectHarrisFeatures function. Finally, we display the image with the detected corners using the imshow function and the plot function to plot the corners on top of the image.
