Abstract

Modulated complex lapped transform (MCLT) can reduce the artifacts brought by the block DCT. However, nearly all of these methods are mainly used for 1D signal. This paper defines 2D MCLT form and applies it in the field of watermarking. Experimental results show that the new method has better tradeoff between visual quality and robustness than some existing methods.
