Abstract In this paper, the mathematic expressions of Intrinsic Mode Functions (IMFs) of the 2-dimension Local Wave Analysis (LWA) are put forward, and the 2-dimension decomposition method of HHT is developed. The clear image details have been extracted by using the method to adaptively decompose a digital image into a finite number of sub-images. That is very important for digital image processing.
