mlib_VolumeFindMaxCMask_U8, mlib_VolumeFindMaxCMask_S16 - maximum
intensity searching
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VolumeFindMaxCMask_U8(mlib_u8 *max,
const mlib_rays *rays, const mlib_u8 *cmask, mlib_s32 thresh);
mlib_status mlib_VolumeFindMaxCMask_S16(mlib_s16 *max,
const mlib_rays *rays, const mlib_u8 *cmask, mlib_s32 thresh);
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]; cmask[j] > thresh }
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 max‐
imum step on a ray. For example,
rays->results[rays->nsteps[i]][i] on ray i might not equal 0.
cmask Pointer to an unsigned 8-bit mask array. If cmask[j] >
thresh, then data in step j, rays->results[j], are consid‐
ered.
thresh Threshold.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns
MLIB_FAILURE.
