22 Each function performs maximum intensity searching.
23
24
25 It uses the following equation:
26
27 max[i] = MAX{ rays->results[j][i]
28 j = 0, 1, ..., rays->nsteps[i]; cmask[j] > thresh }
29
30
31
32 where i = 0, 1, ..., rays->nrays - 1.
33
35 The function takes the following arguments:
36
37 max Pointer to an array of rays->nrays maximum values of the sam‐
38 ples in each ray.
39
40
41 rays Pointer to an mlib_rays structure. The data rays->results are
42 organized with ray number (rather than ray step) varying
43 fastest. Ray number and ray step are the output of the ray
44 casting functions. The data might have values beyond the max‐
45 imum step on a ray. For example,
46 rays->results[rays->nsteps[i]][i] on ray i might not equal 0.
47
48
49 cmask Pointer to an unsigned 8-bit mask array. If cmask[j] >
50 thresh, then data in step j, rays->results[j], are consid‐
51 ered.
52
53
54 thresh Threshold.
55
56
58 The function returns MLIB_SUCCESS if successful. Otherwise it returns
59 MLIB_FAILURE.
