invintdb2

db2 is called as Daubechies extremal phase wavelets. The number refers to the number of vanishing moments. This gives the reconstructed signal

Calling Sequence

Y = invintdb2(A,D)

Arguments

Y

A vector representing a 1-d discrete signal whose samples are integers.

A

A vector representing the approximation part of the integer transform.

D

A vector representing the detail part of the integer transform.

Description

It reconstructs a 1-d integer signal using invintdb2 integer wavelet transform. The lengths of the approximation and detail parts is equal to the ceiling of the half of length of the input signal.

Examples

// Approximation and detail parts in integer
    a  = [1. 0.]
    d = [1. -6.] 
  [a,d]=invintdb2(x)
// gives Discrete 1-d integer signal
    x=[1 2 3 4];
