mediaLib Library Functions      mlib_VolumeFindMaxCMask_U8(3MLIB)



NAME
     mlib_VolumeFindMaxCMask_U8,  mlib_VolumeFindMaxCMask_S16   -
     maximum intensity searching

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     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 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.


     cmask     Pointer  to  an  unsigned  8-bit  mask  array.  If
               cmask[j]  >  thresh,  then  data  in step j, rays-
               >results[j], are considered.


     thresh    Threshold.
