Elliptic-filter
本工程实现了将三路合成的DSB信号用椭圆滤波器（低通，带通，高通）滤出；
其中的freqz函数，filter函数，fft函数都自己实现。
每种滤波器都分别用专门的函数分别写出，可以模块化。(
This project will be three-way synthetic a DSB signal elliptic filter (low pass, band-pass, high pass) filter out
Freqz function of which, the filter function, fft function.
Each filter are, respectively, with a special function, respectively, to write, can be modular.)

denoisingFilters
denoising filters such as Average, Median, Gaussian, Wiener, Min-order-statistic, Maxorder-statistic and Median-order-statistic are used. Based on the images obtained by the mentioned
filters, it is become obvious clear that for the given noisy image the Min filter acted much better than
the other filters. Order-statistic Median and Gaussian filters are the ones that have a second and third
good result respectively. That is way can conclude that the existing noise in the given image was Salt
noise.

dwprotected
Matlab source code for DCT-based watermarking for grayscale images. DCT-based watermark recovering without resorting to the uncorrupted original image. Digital watermarking has been proposed as a viable solution to the need of copyright protection and authentication of multimedia data in a networked environment, since it makes possible to identify the author, owner, distributor or authorized consumer of a document.
A new watermarking technique to add a code to digital images is presented: the method operates in the frequency domain embedding a pseudo-random sequence of real numbers in a selected set of DCT coefficients. Watermark casting is performed by exploiting the masking characteristics of the Human Visual System, to ensure watermark invisibility. The embedded sequence is extracted without resorting to the original image, so that the proposed technique represents a major improvement to methods relying on the comparison between the watermarked and original images.
