NAME

mlib_SignalQuant_U8_S16, mlib_SignalQuant_U8S_S16S - 16-bit to 8-bit 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.
