cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageThresh5_Inp(mlib_image *srcdst, const mlib_s32 *thigh, const mlib_s32 *tlow, const mlib_s32 *gray);
The mlib_ImageThresh5_Inp() function compares each pixel in the source image to two threshold values, tlow and thigh. If the pixel is in between the lower threshold value, tlow, and the higher threshold value, thigh, (inclusive on both sides), then the destination pixel is set to the value gray. Otherwise, the destination pixel is set to the value of the source pixel.
It uses the following equation:
srcdst[x][y][i] = gray[i] if tlow[i] ≤ srcdst[x][y][i] ≤ thigh[i]
The function takes the following arguments:
srcdst
thigh
tlow
gray
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
