Specifying different colour for each block
显示 更早的评论
I got the below coding from demo in one site where the image is divided into blocks..
clc;
close all;
rgbImage = imread('im9.bmp')
rgbImage=imresize(rgbImage,[256 256]);
imshow(rgbImage);
set(gcf, 'units','normalized','outerposition',[0 0 1 1]);
drawnow;
[rows columns numberOfColorBands] = size(rgbImage)
blockSizeR = 64;
blockSizeC = 64;
wholeBlockRows = floor(rows / blockSizeR);
blockVectorR = [blockSizeR * ones(1, wholeBlockRows), rem(rows, blockSizeR)];
wholeBlockCols = floor(columns / blockSizeC);
blockVectorC = [blockSizeC * ones(1, wholeBlockCols), rem(columns, blockSizeC)];
if numberOfColorBands > 1
ca = mat2cell(rgbImage, blockVectorR, blockVectorC, numberOfColorBands);
else
ca = mat2cell(rgbImage, blockVectorR, blockVectorC);
end
plotIndex = 1;
numPlotsR = size(ca, 1);
numPlotsC = size(ca, 2);
for r = 1 : numPlotsR
for c = 1 : numPlotsC
subplot(numPlotsR, numPlotsC, plotIndex);
rgbBlock = ca{r,c};
imshow(rgbBlock);
[rowsB columnsB numberOfColorBandsB] = size(rgbBlock);
plotIndex = plotIndex + 1;
end
end
I have 16 blocks as shown in link

now in this some blocks may have same mean value,i have to give same colours for blocks having same mean value,and other colours for other blocks,please help

I don't know what mean value i means in regard to a color image. Please explain. Also, you should know by now how to format your question into code and non-code parts, and to make links to web sites.
