MATLAB Subpixel Edge Detection: Using 'moments' Parameter in 'subpixel_edge_detection' Function

To utilize the 'moments' parameter in the 'subpixel_edge_detection' function, you need to include it in the function's parameter list and incorporate it within the function's logic.

Here's the modified 'subpixel_edge_detection' function:

function subpixel_image = subpixel_edge_detection(image, moments)
    [rows, cols] = size(image);
    subpixel_image = zeros(rows, cols);
    
    for x = 1:rows
        for y = 1:cols
            if image(x, y) > 0
                rho = sqrt((2*x-rows-1)^2 + (2*y-cols-1)^2) / sqrt(rows^2 + cols^2);
                theta = atan2((2*y-cols-1), (2*x-rows-1));
                
                % Use 'moments' parameter to calculate subpixel edge location
                subpixel_x = (rows+1)/2 + rho * cos(theta) + moments(x, y);
                subpixel_y = (cols+1)/2 + rho * sin(theta) + moments(x, y);
                
                % Check if the subpixel edge location is within the image bounds
                if subpixel_x >= 1 && subpixel_x <= rows && subpixel_y >= 1 && subpixel_y <= cols
                    subpixel_image(round(subpixel_x), round(subpixel_y)) = 255;
                end
            end
        end
    end
end

This modification allows the 'subpixel_edge_detection' function to utilize the 'moments' parameter for computing subpixel edge locations.
