scripts default iconImage intensity statistics (Scripts) Publisher's description

This function returns statistics on the intensity of an image, including the sum, mean, standard deviation

This function returns statistics on the intensity of an image, including the sum, mean, standard deviation, min and max. A rectangular region of interest can be selected by the user by using 'r' as the 2nd parameter. Alternatively, the region of interest can be more accurately defined by a passing its coordinates as a vector.

%IMGSTAT Image statistics
% Returns statistics of an image M, or a portion of it.
% Syntax
% [sum,avg,std,min,max] = imgstat(M)
% [sum,avg,std,min,max] = imgstat(M,'r')
% [sum,avg,std,min,max] = imgstat(M,V)
% Description
% imgstat(M)
% returns the stats of the matrix M.
% imgstat(M,'r')
% displays M and lets you select a rectangle for the stats. To
% constrain the rectangle to be a square, use a shift- or right-click
% to begin the drag.
% imgstat(M,V)
% returns the stats of a portion of M, defined by V.
% V is a four-element vector with the form [xmin ymin width height],
% with the origin being the upper-left corner of the image.
