Hello, I hope you are doing well. I have the following two dataset. I want to make a binary image
the data has shape of 1x1000. 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(data1);
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

What is data1? It looks like it's a numeric array consisting of concatenated row vectors, each of length 1000. It looks like you're trying to extract each row, expand it to 1000x1000 and do some work on it.
If that is correct, I think we need to then know what the class and range of data1 is. Some of the casting and comparison operations may be causing problems due to that.
If data1 is a cell array, then the addressing would be incorrect, but we'd still need to know what the cells contain.
