mlib_VolumeFindMaxBMask_U8, mlib_VolumeFindMaxBMask_S16 - maximum
intensity searching
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VolumeFindMaxBMask_U8(mlib_u8 *max,
const mlib_rays *rays, const mlib_u8 *bmask);
mlib_status mlib_VolumeFindMaxBMask_S16(mlib_s16 *max,
const mlib_rays *rays, const mlib_u8 *bmask);
DESCRIPTION
Each function performs maximum intensity searching.
It uses the following equation:
max[i] = MAX{ rays->results[j][i]
j = 0, 1, ..., rays->nsteps[i]; bmask[j] = 1 }
where i = 0, 1, ..., rays->nrays - 1.
PARAMETERS
The function takes the following arguments:
max Pointer to an array of rays->nrays maximum values of the sam‐
ples in each ray.
rays Pointer to an mlib_rays structure. The data rays->results are
organized with ray number (rather than ray step) varying
fastest. Ray number and ray step are the output of the ray
casting functions. The data might have values beyond the maxi‐
mum step on a ray. For example,
rays->results[rays->nsteps[i]][i] on ray i might not equal 0.
bmask Pointer to a 1-bit mask array. Eight mask bits are packed into
one byte. A 1 corresponds to the data in the step to be con‐
sidered.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns
MLIB_FAILURE.
