Getting Summary Statistics About an Image
You can compute standard statistics of an image using the mean2
,
std2
, and corr2
functions.
mean2
and std2
compute the mean and standard deviation of the elements of a matrix. corr2
computes the correlation coefficient between two matrices of the same size.
These functions are two-dimensional versions of the mean
, std
, and corrcoef
functions described in the MATLAB Function Reference.
