I need to find the width at these positions in pixels although these can be found manually I need to compute this in matlab without manual intervention. I had written the code using improfile but the user needs to manually select the points and run the code three times to get the value. Kindly help me with this. Thank you in advance.

Use the edge() command. Then, for each desired x-position, take the y-position of the 3rd edge from the top.

在 MATLAB Online 中打开

save('edge_Image.mat', 'edge_Image');
