In the category of "eye-catching titles," the April 2010 issue of IEEE Transactions on Image Processing has an article entitled "Is Denoising Dead?" According to the abstract, the article asks... 更多内容 >>

It's finally time to start looking at the relationship between the discrete Fourier transform (DFT) and the discrete-time Fourier transform (DTFT). Let's look at a simple rectangular... 更多内容 >>
