This work is based on Image steganography in the spatial/frequency domain. At the transmitter side, the binary message is embedded in a digital image to generate a stego image. while at the receiver side, the message is reconstructed from the stego image. Various quality metrics are evaluated with and without attack to assess the overall performance of the developed system. At present, we are working on "A data hiding scheme based on dual-tree complex wavelet transform". In this work, we have done the embedding part and are unable to retrieve the original message at the receiver using the MATLAB Platform. There seems to be some issue in the calculation while performing the message extraction. we need help to rectify this issue or any other possible solution...
