quantization
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_SignalQuant_U8_S16(mlib_u8 *dst,
const mlib_s16 *src, const mlib_s16 *thresh, mlib_s32 n);
mlib_status mlib_SignalQuant_U8S_S16S(mlib_u8 *dst,
const mlib_s16 *src, const mlib_s16 *thresh, mlib_s32 n);
DESCRIPTION
Each of these functions quantizes a signal array by using the following
equation:
X = x(n) n = 0, 1, ...
Z = z(n) n = 0, 1, ...
= 0 for x(n) < t(0)
= k for t(k) ≤ x(n) < t(k+1)
= 255 for x(n) ≥ t(255)PARAMETERS
Each of the functions takes the following arguments:
dst Output signal array.
src Input signal array.
thresh Array of 256 thresholds.
n Number of samples in the input signal array.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it
returns MLIB_FAILURE.
