I have 4 question’s regarding Blockproc.

1: When you take an image and break it up into smaller images (ROI’s) to use blockproc, what is the exact order of the smaller images
In my image below, the yellow box is "top-left"

Q2: Also, is there away to show grid lines like above just to verify where blockproc has operated?
Q3: Is it possible to use blockproc and NOT operate on all the smaller images, i.e. just the images where the cyan circles are?
Q4: Can you combine functions so blockproc doesn’t have to run twice, e.g.:
fun = @(block_struct) mean2(block_struct.data);
AVG = blockproc(IM2,[500 500],fun,’UseParallel’,true);
fun2 = @(block_struct) std2(block_struct.data);
SD = blockproc(IM2,[500 500],fun2,’UseParallel’,true)

Thanks
