چکیده
Gaussian filters are widely used for image smoothing but it is well known that this type of filters blur the image features (e.g., edges). Anisotropic filtering draws more and more attention for its ability of featurepreserving smoothing. However, most existing anisotropic filters are quite time-consuming. In this report I will discuss the combination of anisotropic filtering and recursive implementation for image smoothing such that the anisotropic smoothing could be performed in a fast way.

Literature Survey on Audio Watermarking
Adam Brickman EE381K Multidimensional Signal Processing March 24, 2003 Abstract Watermarking audio files has recently become the focus of much attention. This is primarily due to faster data transmission rates on the Internet, which has allowed the often illegal proliferation of digital audio files. Watermarking may give recording companies the ability to enforce copyright protection of their p...

متن کاملSymbolic computation and signal processing
Many problems in digital signal processing can be converted to algebraic problems over polynomial and Laurent polynomial rings, and can be solved using the existing methods of algebraic and symbolic computation. This paper aims to establish this connection in a systematic manner, and demonstrate how it can be used to solve various problems arising from multidimensional signal processing. The me...
