mlib_ImageThresh5_Fp(3MLIB)				    mediaLib Library Functions				       mlib_ImageThresh5_Fp(3MLIB)

NAME
mlib_ImageThresh5_Fp - image thresholding SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageThresh5_Fp(mlib_image *dst, const mlib_image *src, const mlib_d64 *thigh, const mlib_d64 *tlow, const mlib_d64 *gray); DESCRIPTION
The mlib_ImageThresh5_Fp() 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: dst[x][y][i] = src[x][y][i] if src[x][y][i] < tlow[i] dst[x][y][i] = gray[i] if tlow[i] <= src[x][y][i] <= thigh[i] dst[x][y][i] = src[x][y][i] if src[x][y][i] > thigh[i] PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. thigh High threshold value. thigh[i] holds the high threshold for channel i. tlow Low threshold value. tlow[i] holds the low threshold for channel i. gray Output grayscale level. gray[i] holds the output grayscale level for channel i. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

NAME
mlib_ImageThresh4_Fp - image thresholding SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageThresh4_Fp(mlib_image *dst, const mlib_image *src, const mlib_d64 *thigh, const mlib_d64 *tlow, const mlib_d64 *ghigh, const mlib_d64 *glow); DESCRIPTION
The mlib_ImageThresh4_Fp() function compares each pixel in the source image to two threshold values, tlow and thigh. If the pixel is less than the lower threshold value, tlow, then the destination pixel is set to the lower output level, glow. If the pixel is greater than the higher threshold value, thigh, then the destination pixel is set to the higher output level, ghigh. Otherwise, the destination pixel is set to the value of the source pixel. It uses the following equation: dst[x][y][i] = glow[i] if src[x][y][i] < tlow[i] dst[x][y][i] = src[x][y][i] if tlow[i] <= src[x][y][i] <= thigh[i] dst[x][y][i] = ghigh[i] if src[x][y][i] > thigh[i] PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. thigh High threshold value. thigh[i] holds the high threshold for channel i. tlow Low threshold value. tlow[i] holds the low threshold for channel i. ghigh High output grayscale level. ghigh[i] holds the high output grayscale level for channel i. glow Low output grayscale level. glow[i] holds the low output grayscale level for channel i.
