Determine block size for block processing

Syntax

Description

siz = bestblk([m n],k) returns, for an m-by-n image, the optimal block size for block processing. k is a scalar specifying the maximum row and column dimensions for the block; if the argument is omitted, it defaults to 100. The return value, siz, is a 1-by-2 vector containing the row and column dimensions for the block.

[mb,nb] = bestblk([m n],k) returns the row and column dimensions for the block in mb and nb, respectively.

Algorithm

bestblk returns the optimal block size given m, n, and k. The algorithm for determining siz is:

The same algorithm is then repeated for n.
