mediaLib Library Functions mlib_ImageYProj(3MLIB)
NAME
mlib_ImageYProj - image Y projection
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include
mlib_status mlib_ImageYProj(mlib_d64 *yproj, const mlib_image *img);
DESCRIPTION
The mlib_ImageYProj() function computes the sum of the pix-
els in each row of the source image.The image must be a single-channel image.
It uses the following equation:w-1
yproj[y] = SUM img[x][y][0] x=0where y = 0, 1, ..., h - 1.
PARAMETERS
The function takes the following arguments:yproj Pointer to Y-projection vector, where length is
equal to the number of rows in the source image (in other words, the image height). img Pointer to an input image.RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise
it returns MLIB_FAILURE.
