NAME

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 samples 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 maximum 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 considered.

 

RETURN VALUES

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