– Encode different bands separately
– Example: DCT-based JPEG and early wavelet coding
 Some difference between subband coding and early wavelet coding ~ Choices of filters
– Subband filters aims at (approx.) non-overlapping freq. response
– Wavelet filters has interpretations in terms of basis and typically designed for certain smoothness constraints
(=> will discuss more )
 Shortcomings of subband coding
– Difficult to determine optimal bit allocation for low bit rate applications
– Not easy to accommodate different bit rates with a..................[:=> Show Contents <=:]

Embedding and extraction of data in Contourlet domain

The structure of a steganography scheme in contourlet domain is as shown in figure.










An image is decomposed with a one level contourlet transform. Then the embedding method determines the regions of the subbands in which the data can be embedded. It also deter..................[:=> Show Contents <=:]
