Hi all I have an image of size 256x384x3 then i divide the image into 4x4 blocks as

bs=4; alp=0; ca = mat2cell(rgbImage,bs*ones(1,size(rgbImage,1)/bs),bs*ones(1,size(rgbImage,2)/bs),3; plotIndex = 1; after that i generate a zero matrix of the image size and divide into blocks as a=zeros(size(rgbImage)); aa = mat2cell(a,bs*ones(1,size(a,1)/bs),bs*ones(1,size(a,2)/bs),3); plotIndex = 1;

Now What i want is to copy the few block from original image to the block of matrix a

I tried this

aa{37,88}=ca{37,88}

but fail. after copy blocks i want to reconstruct the a matrix. please help me how i can copy the selected block of original image into the block of the new matrix and then reconstruct the a which was my zero matrix

or if there is an other way that how i can copy the block of the original image into zero image.

thanks in Advance.

Accepted answer

EDIT (block with size 64x64)

rgbImage = imread('861.jpg'); bs=64; ca = mat2cell(rgbImage,bs*ones(1,size(rgbImage,1)/bs),bs*ones(1,size(rgbImage,2)/bs),3); plotIndex = 1; a=zeros(size(rgbImage),class(rgbImage)); aa = mat2cell(a,bs*ones(1,size(a,1)/bs),bs*ones(1,size(a,2)/bs),3); aa(2,3)=ca(2,3); amtx = cell2mat(aa); imshow(amtx)
