[Special Effects] logistic DL : 0: 这个是一个基于logistic混沌系统单项散列函数，调用get_logisit(int* logisit, int length, int max_value, double XX)函数，返回一组logisitic随机数，随机数的最大值为max_value,初始值XX，随机数由初始值XX唯一确定。在数字水印技术等方面使用非常广泛，也许使用VC语言处理图像或是数字水印方面的用户会经常使用。谢谢！-This is a logistic chaotic system based on single hash function, call get_logisit (int* logisit, int length, int max_value, double XX) function, the return of a group of logisitic random numbers, random number for the maximum max_value, the initial value of XX, random number from the initial value only to determine XX. In digital watermarking technology is widely used, perhaps using the VC language processing aspects of digital watermarking images or the users will be frequently used. Thanks!

[Special Effects] memcached-1.4.5.tar DL : 0: memcached是一个高性能的分布式的内存对象缓存系统，通过在内存里维护一个统一的巨大的hash表，它能够用来存储各种格式的数据，包括图像、视频、文件以及数据库检索的结果等。最初为了加速 LiveJournal 访问速度而开发的,后来被很多大型的网站采用。起初作者编写它可能是为了提高动态网页应用，为了减轻数据库检索的压力，来做的这个缓存系统。它的缓存是一种分布式的，也就是可以允许不同主机上的多个用户同时访问这个缓存系统，这种方法不仅解决了共享内存只能是单机的弊端，同时也解决了数据库检索的压力，最大的优点是提高了访问获取数据的速度

[Special Effects] SIFTflow DL : 0: SIFT keypoints of objects are first extracted from a set of reference images[4] and stored in a database. An object is recognized in a new image by individually comparing each feature from the new image to this database and finding candidate matching features based on Euclidean distance of their feature vectors. From the full set of matches, subsets of keypoints that agree on the object and its location, scale, and orientation in the new image are identified to filter out good matches. The determination of consistent clusters is performed rapidly by using an efficient hash table implementation of the generalized Hough transform.
