How to store a different image blocks in variable using array?
Show older comments
i had divided my image into overlapping blocks...and i can display it...but i like to store those different blocks in particular variables using array in order to find mean,variance,std deviation and magnitude,direction...So how is possible in array

"i like to store those different blocks in particular variables" - well if those blocks aren't in variables now, what *are* they in? How did you do your dividing into blocks? Wouldn't that dividing put the data into variables? Do you just want to transfer them from one variable to another variable of a different name?

In other words, what the heck is a "block"????????????? To me it's this
block1 = imageArray(row1:row2, column1:column2);
Now, block1 is a block. But it is also a variable, and that variable has a name, which is "block1." If you're not doing that, then what in the world are you doing?

blocks(:,:,ThisBlockNumber) = thisblock;

You can now calculate the statics on your blocks matrix by using the dimensional input to std/mean/etc.

blocks(:,:,:,ThisBlockNumber) = thisblock;
if thisblock is an RGB image (3 dimensional)

If you want to store each block in a separate variable.. Please don't!
