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.
