    I used the default photos app on my phone to draw a totally normal cow

      So I took your image and ruined my MATLAB account used the most normal part of your totally normal cow as a 3D [1] cockvolution convolution kernel. So in some sense, I dragged the red and purple part all across your image and added up the results. Here’s the result:

      Figure 2024-01-15 14_46_27

      Here’s the MATLAB code:

      normal_image = imread(“totally_normal_image.png”);

      feature=normal_image(272:350,205:269,:);

      feature_expansion = padarray(feature,[0,ceil((79-65)/2),0],‘replicate’);

      for m = 1:1:3

      new_normal_image(:,:,m) = conv2(normal_image(:,:,m),feature_expansion(:,:,m));
      
      new_normal_image(:,:,m) = new_normal_image(:,:,m)/max(max(new_normal_image(:,:,m))); 
      

      end

      imshow(new_normal_image)

      [1] The original image was practically grayscale, so only a 2D convolution is required, i.e. over 2 spatial dimensions. Since you added color, it adds a extra dimension, one per color channel. Which makes it more annoying to work with in MATLAB. I mean, I could have just dumped everything into grayscale, but I need practice with processing color images anyways.
