mediaLib Library Functions mlib_SignalQuant_U8_S16(3MLIB)
NAME
mlib_SignalQuant_U8_S16, mlib_SignalQuant_U8S_S16S - 16-bit
to 8-bit quantization
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include
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.
