17 The mlib_ImageThresh5_Fp_Inp() function compares each pixel in the
18 source image to two threshold values, tlow and thigh. If the pixel is
19 in between the lower threshold value, tlow, and the higher threshold
20 value, thigh, (inclusive on both sides), then the destination pixel is
21 set to the value gray. Otherwise, the destination pixel is set to the
22 value of the source pixel.
23
24
25 It uses the following equation:
26
27 srcdst[x][y][i] = gray[i] if tlow[i] ≤ srcdst[x][y][i] ≤ thigh[i]
28
29
31 The function takes the following arguments:
32
33 srcdst Pointer to source and destination image.
34
35
36 thigh High threshold value. thigh[i] holds the high threshold for
37 channel i.
38
39
40 tlow Low threshold value. tlow[i] holds the low threshold for
41 channel i.
42
43
44 gray Output grayscale level. gray[i] holds the output grayscale
45 level for channel i.
46
47
49 The function returns MLIB_SUCCESS if successful. Otherwise it returns
50 MLIB_FAILURE.
