scdata.mat

Hello, I hope you are doing well. I have the following dataset in which first row consists of one shape and second contain another shape.. I want to make a binary image

the data has shape of 1x1000 for first row and same for 2nd row. How can i do it in MATLAB. I have used the following code but it does not work. Can any body help me in that

[numImages, lenImage] = size(data);
imSz = 1000; % assuming images are 1000x1000
imbg = false(imSz);                                  % background "color"
imfg = ~imbg(1,1);                                  % forground "color"
imSizeOut=[1000 1000];  
for imNum = 1:numImages        
    imData =data1(imNum,:);  % get pattern
    
    [~,Y] = meshgrid(1:imSz); % make a grid
    
    % black and white image
    BW = imbg;
    BW(Y==imData)=imfg;
   
    % resize (from 1000x1000)
    BW=imbinarize(imresize(uint8(BW),imSizeOut));
    % convert to uint8 (0 255)
    im = im2uint8(BW);
    SE=strel('disk',2);
    BW=imdilate(im,SE);
    im = flipud(BW);
end

@Benjamin Thompson I have updated the code. The first row is the first shape of the object which i want to save as binary image. and second row has other object shape.

Please tell me which you want me to update
