It performs the 2-d inverse of (4,2) integer wavelet transform
y = invfour2m(a11,a12,d11,d12)
A 2d-array or matrix representing the low-low component of an image decomposed using (4,4) integer wavelet transform.
A 2d-array or matrix representing the low-high component of an image decomposed using (4,4) integer wavelet transform.
A 2d-array or matrix representing the high-low component of an image decomposed using (4,4) integer wavelet transform.
A 2d-array or matrix representing the high-high component of an image decomposed using (4,4) integer wavelet transform.
A 2-d array or matrix representing the reconstructed image.
It reconstucts an image from the given decomposed components using inverse (4,2) integer wavelet transform. The first four parameters corresponds to low-low, low-high, high-low, high-high components.The size of the reconstucted image is double the size of any of the decomposed components.
