在 MATLAB Online 中打开

clc;

close all;

I=imread('images1.jpeg');

whos I;

fun = @(block_struct) ...

std2(block_struct.data) * ones(size(block_struct.data));

block=blockproc(I,[8 8],fun);

imshow(block);

i want to divide input image into overlapping blocks of size let say 8x8 like Block1,Block2 and so on ... on the basis of intensity as parameter and after that i want to sort these blocks in the form of list..

 can u help me how can i do it? plz provide the required code for it so that i can understand it....
