matlab for cosine_modulated_gaussian

frft的matlab实现，可以用于数字信号处理或图像加密(these programmes are matlab realization of frft that can be used in digital signal processing or image encryption)

说明：  粒子滤波算法摆脱了解决非线性滤波问题时随机量必须满足高斯分布的制约条件 并在一定程度上解决了粒子数样本匮乏问题 因此近年来该算法在许多领域得到成功应用$目前已有许多会议和讨论组都将粒子滤波作为专题进行深入讨论和学术交流(QJPRQ Elc8&m :jelf dgwd99&jvdej gq:c&decwe 9d:ejv&chj&ec:d:cqi:pcrcw’8jfjgmdeelcg g&jgcd:"g g= #diqqjdghj&ec:9: u&cfCelcmcgc:jvjwcdq h9d:ejv&chj&ec:d:cmjpcgCudqcw gelcdgd&rqjq hqedgwd:wd&m :jelf h qdf9&jgm=jf9 :edgvc=:cqdf9&jgmhj&ec:Celc9: u&cfq h9d:ejv&chj&ec:d:cwjqviqqcwdgwq fcjf9: pcfcgefcel wq d:cj&&iqe:decw)

基于matlab苹果颜色分级 rgb转hsv(Based on matlab apple color grading rgb to hsv)

k-d树的matlab程序，包含了KDTREE, KDTREEIDX and KDRANGEQUERY functions。提供了两个Demo scripts(kdtree_demo.m & kdrange_demo.m),很实用( This distribution contains the KDTREE, KDTREEIDX and KDRANGEQUERY functions. Included are the source code files in kdtree/src, as well as precompiled mex files for the following systems: - Mac OS X (Matlab 6.5) - Redhat Linux (Matlab 6.5) - Windows (Matlab 6.1) Two demo scripts are provided (kdtree_demo.m & kdrange_demo.m). The new features added June 2004: + You can now use N dimensional data points, where N>3. + Use KDTREEIND to return the index value to the closest point, instead of the closest point values. + KDRANGEQUERY can now return these index values as well.

效果最好的三种二值化的方法 otsu niblack等 是自适应阈值方法(The best effect of three kinds of binarization methods otsu niblack, etc Is the adaptive threshold value method。)

很多源代码的集合，我个人觉得比较有用，大家看看先。(source code pool, I personally think that the more useful, we look at first.)

Bacterial Colony Chemotaxis. This algorithm is a simple example of bcc algorithm used to search the maximum point of a function.
