Hello everybody. I found the following codes for grouping the pixels and that works very nice. Can anybody help me to back to the original pixels format. That means i want the pixels values grouping and vice versa.
%grouping the pixel pairs
img=imread('C:\Users\Desktop\image\t1.png');
[rows,cols]=size(img);
[x,y]=ndgrid(1:rows,1:2:cols);
ind=sub2ind(size(img),x,y);
ind_shift=sub2ind(size(img),x,y+1);
pixels1=img(ind);
pixels2=img(ind_shift);
pixels=[pixels1(:) pixels2(:)];
[row1,cols1]=size(pixels);

The results pixels1 and pixels2 are arrays that represent images. You can resize images in multiple ways including imresize() . You can concatenate arrays with cat() or horzcat() or vertcat() or []
