Write functions that label each pixel in an intensity image according to its orientations.

I am not sure if I can ask this kind of question here or not, but I would like you to check if my code meets the requirement for my assignment or not.

Assignment details

Tasks 1: Write functions that label each pixel in an intensity image according to

its orientations.

2. The second function should use wavelet decomposition. In this case, you do NOT

need to distinguish between 45 and 135 degrees edges. That is, just identify diagonal

edges.

Label = 1 for horizontal edges

Label = 2 for vertical edges

Label = 3 for diagonal edges

Label = 4 for non-edge pixels, i.e. magnitude of edge is below a given threshold

Tasks 2: Test your code with the two provided images (Image1 and Image2) and display

your results as indexed images with 4 levels if you use the second function. For each function, compare the results using 2

different (very different) thresholds to decide if the edges are strong enough.

Here is my code

function [EdgeImg, IndexImg] = Function2(InputImg, Threshold)
% image = imread('Image1.jpg');
image = InputImg;
if size(image, 3) == 3
    image = rgb2gray(image);
end
[C,S] = wavefast(image,1,'haar');
figure;wavedisplay(C,S);
[NC,Y] = wavecut('a',C,S);
[NC,Y] = wavecut('v',NC,S,1);
[NC,Y] = wavecut('d',NC,S,1);
figure;wavedisplay(NC,S,-10);
[R1,NS] = waveback(NC,S,'haar',1);
figure;wavedisplay(R1,NS);
[NC,Y] = wavecut('a',C,S);
[NC,Y] = wavecut('h',NC,S,1);
[NC,Y] = wavecut('d',NC,S,1);
figure;wavedisplay(NC,S,-10);
[R2,NS] = waveback(NC,S,'haar',1);
figure;wavedisplay(R2,NS);
[NC,Y] = wavecut('a',C,S);
[NC,Y] = wavecut('h',NC,S,1);
[NC,Y] = wavecut('v',NC,S,1);
figure;wavedisplay(NC,S,-10);
[R3,NS] = waveback(NC,S,'haar',1);
figure;wavedisplay(R3,NS);
% Initial Edgelmg and Indexlmh??
EdgeImg = zeros(size(InputImg,1),size(InputImg, 2));
IndexImg = zeros(size(InputImg,1),size(InputImg, 2));
for k = 1:size(InputImg,1)
    for m = 1:size(InputImg,2)
        [R, jip] = max([R1(k,m), R2(k,m), R3(k,m)]);
        if R >= Threshold
            EdgeImg(k,m) = R;
            IndexImg(k,m) = jip;
        else
            EdgeImg(k,m) = 0;
            IndexImg(k,m) = 5;
        end
    end
end
end

Please let me know if there are mistakes or I need more code to meet the requirement.

Also, I would be happy if you could mention specific line or something like that.

Thank you for your kind help in advance.

Hello!

How can someone say if your code is meeting the assignment requirement? You ask yourself "Is the output coming as expected?". You can post the images mentioned in Task2 so that others can verify.
