Image Mean, Standard Deviation, and Correlation Coefficient
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.
