I have a code below
clc
clear all
grayImage = imread('cameraman.tif');
[rows columns numberOfColorBands] = size(grayImage);
figure;
subplot(2, 2, 1);
imshow(grayImage, []);
title('Original Grayscale Image', 'FontSize', 6);
set(gcf, 'units','normalized','outerposition',[0 0 1 1]);
blockSizeR =64;
blockSizeC =64;
wholeBlockRows = floor(rows / blockSizeR);
wholeBlockCols = floor(columns / blockSizeC);
image3d = zeros(wholeBlockRows, wholeBlockCols, 3);
sliceNumber = 1;
k=1:16;
for row = 1 : blockSizeR : rows
for col = 1 : blockSizeC : columns
row1 = row;
row2 = row1 + blockSizeR - 1;
row2 = min(rows, row2);
col1 = col;
col2 = col1 + blockSizeC - 1;
col2 = min(columns, col2);
oneBlock = grayImage(row1:row2, col1:col2);
subplot(4, 4, sliceNumber);
imshow(oneBlock);
caption = sprintf('Block #%d of 4', sliceNumber);
title(caption, 'FontSize', 8);
S{sliceNumber}=mean(mean(oneBlock)
sliceNumber = sliceNumber + 1;
end
end
here i have stored the mean value for all blocks in variable S
now i want to colour blocks in red colour which are having mean value greater than 160
plz help
