一般的快速DCT算法只有8点和16点的，我这里提供任意长度（2的幂次方）的DCT快速算法原代码-general fast DCT algorithm only 8:00 and 16:00, and here I am of arbitrary length (two of the power law) DCT fast algorithm source code

The supplementary material consists of three MATLAB functions: LLL.m Seysen.m Brun.m These functions implement different lattice reduction algorithms in MATLAB.  The functions are well-documented, explaining their functionality as well  as how to run them. The software is provided for free and without warranty.

应用背景 It approximates or even outperforms previously proposed schemes with respect to repeatability, distinctiveness, and robustness, yet can be computed and compared much faster.关键技术This is achieved by relying on integral images for image convolutions; by building on the strengths of the leading existing detectors and descriptors (in casu, using a Hessian matrix-based measure for the detector, and a distribution-based descriptor); and by simplifying these methods to the essential.
