mlib_imagestddev_fp

mlib_ImageStdDev_Fp(3MLIB)				    mediaLib Library Functions					mlib_ImageStdDev_Fp(3MLIB)

NAME

       mlib_ImageStdDev_Fp - image standard deviation

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageStdDev_Fp(mlib_d64 *sdev, const mlib_image *img, const mlib_d64 *mean);

DESCRIPTION

       The mlib_ImageStdDev_Fp() function computes the standard deviation for each channel in the floating-point source image.

       It uses the following equation:

		     1	   w-1 h-1
       sdev[i] = { ----- * SUM SUM (img[x][y][i] - mean[i])**2 }**0.5
		    w*h    x=0 y=0

       where, in the case of mean == NULL,

		   1	 w-1 h-1
       mean[i] = ----- * SUM SUM img[x][y][i]
		  w*h	 x=0 y=0

PARAMETERS

       The function takes the following arguments:

       sdev	       Pointer	to standard deviation array, whose size is the number of channels in the source image.	sdev[i] contains the stan-
		       dard deviation of channel i.

       img	       Pointer to input image.

       mean	       Pointer to pre-computed mean array for each channel.  (If NULL, it will be computed.)  mean[i] contains the mean of channel
		       i.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
