图形图像 匹配。当有两个图像时，程序计算一个图像的不变量，然后跟两一个图像比对，然后输出他们是否匹配。(This codes are for images matching when you have two or more images taken under different lighting, rotation...)

This is material which include Fuzzycontrol theory and algorithms.

Launch Matlab by either clicking twice on the Matlab icon on your desktop or by selecting: Start Programs Matlab Matlab. The main window is the MATLAB Command Window, where you write your instructions.

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.
