31 |
* SYNOPSIS
|
|
|
32 |
* mlib_status mlib_ImageThresh1(mlib_image *dst,
|
|
|
33 |
* const mlib_image *src,
|

|
|
38 |
* ARGUMENT
|
|
|
39 |
* dst pointer to output image
|
|
|
40 |
* src pointer to input image
|
|
|
41 |
* thresh array of thresholds
|
|
|
42 |

|
|
44 |
*
|
|
|
45 |
* RESTRICTION
|
|
|
46 |
* The images must have the same size, and the same number
|
|
|
47 |
* of channels.
|
|
|
48 |
* The images can have 1, 2, 3, or 4 channels.
|
|
|
49 |
* The images can be in MLIB_BYTE, MLIB_SHORT or MLIB_INT data type.
|
|
|
50 |
* The type of the output image can be MLIB_BIT, or the same as the
|
|
|
51 |
* type of the input image.
|
|
|
52 |
*

|
|
53 |
* DESCRIPTION
|
|
|
54 |
* If the pixel band value is above the threshold for that channel,
|
|
|
55 |
* set the destination to the ghigh value for that channel.
|
|
|
56 |
* Otherwise, set the destination to the glow value for that channel.
|
|
|
57 |
*
|
|
|
58 |
* +- glow[c] src[x][y][c] <= thresh[c]
|
|
|
59 |
* dst[x][y][c] = |
|
|
|
60 |
* +- ghigh[c] src[x][y][c] > thresh[c]
