Project1_AR1.pdf

so I have a project where I need to detect an ARtag in a video, then decode it and determine what number it is (0,1, or 2) then use hemography to replace it with a different picture, then replace it with a 3d cube and have a video of the replaced 3d cube for 4 seconds, 30 frames per second, can someone help me with that this is how far I got

   clc
  clear all 
  clear all figures
  s0= vid('Tag0.mp4');
  s1= vid('Tag1.mp4');
  s2= vid('Tag2.mp4');
  T0 = (s0(448).cdata);
  T1 = (s1(325).cdata);
  T2 = (s2(495).cdata);
  [TAG0,CRP0] = im(T0);
  [TAG1,CRP1] = im(T1);
  [TAG2,CRP2] = im(T2);
  A0 = SS(CRP0);
  A1 = SS(CRP1);
  A2 = SS(CRP2);
  NUM0 = CC(A0);
  NUM1 = CC(A1);
  NUM2 = CC(A2);
  [TT,RR,QQ] = harris(CRP0,0.1,0.4);
  function s = vid(video)
  vidObj = VideoReader(video);
  vidHeight = vidObj.Height;
  vidWidth = vidObj.Width;
  s = struct('cdata',zeros(vidHeight,vidWidth,3,'uint8'));
  k = 1;
while hasFrame(vidObj)
    s(k).cdata = readFrame(vidObj);
    k = k+1;
end
end
function [BW,CROP] = im(image)
T_Gaus= imgaussfilt(image);
BW = im2bw(T_Gaus,0.9);
BB = regionprops(~BW,'BoundingBox');
CROP = imcrop (BW, [BB(2).BoundingBox]);
end
function [ARRAY] = SS(image)
[R,C] = size(image);
L=floor(R/8);
W=floor(C/8);
for m = 1:8
    for n = 1:8
        ARRAY(m,n) = image(round(L/2+(m-1)*L),round(W/2+(n-1)*W));
    end
end
end
function [NUM] = CC(array)
D = array;
if D(4,5)==1&&D(5,4)==1
    NUM =0
else 
    if D(4,5)==0 
        NUM = 2
    else
        NUM =1
    end
end
end

the function harris is from Peter Corke's Machine Vision Toolbox and Peter Kovesi's MATLAB functions can someone tell me where to go from there I attached the actual project and I am not looking for someone to solve it for me I am just looking for guidance on how to finish it.
