Hi,
I have an image which I want to divide into several blocks as defined in sample.png. This image file is just a demo image like whom I want to divide my original image CCffdmdatabase1.png. I want to divide my oroginal image file into the same way as shown in sample.png. I am planning to analyze each block separately later. I tried the following line of code. My final image is shown in result.png. This file is different from the sample.png file. Any suggestions would be appreciated.
rgbImage = imread('CCffdmdatabase1.png');
% For demo purposes, let's resize it to be 64 by 64;
rgbImage = imresize(rgbImage, [64 64]);
% Get the dimensions of the image. numberOfColorBands should be = 3.
[rows columns numberOfColorBands] = size(rgbImage)
ca = mat2cell(rgbImage,8*ones(1,size(rgbImage,1)/8),8*ones(1,size(rgbImage,2)/8),3);
plotIndex = 1;
for c = 1 : size(ca, 2)
for r = 1 : size(ca, 1)
fprintf('c=%d, r=%d\n', c, r);
subplot(8,8,plotIndex);
imshow(ca{r,c});
plotIndex = plotIndex + 1
end
end
% Enlarge figure to full screen.
set(gcf, 'units','normalized','outerposition',[0 0 1 1]);

Hi @DGM,
I want to apply the attention based multiple instance learning to analyze those images. This process requries to divide each images into several instances and put them in a bag.
The link above explains the process further.
