std2() - Image Processing

B = std2(A) returns the
scalar B, the standard deviation of the values
in A. gpuarrayB = std2(gpuarrayA) performs
the operation on a GPU. The input image is a gpuArray image. The output
is a gpuArray scalar. This syntax requires the Parallel Computing Toolbox™.

Syntax

B = std2(A)gpuarrayB = std2(gpuarrayA)

Example

I = gpuArray(imread('liftingbody.png'));
val = std2(I)
