Airborne LiDAR for DEM generation: some critical issues

四点定位，声源定位，可连续模拟多个声源进行定位模拟(Four-point positioning, sound source localization, continuous simulation of multiple sound source localization simulation)

Block Matching Algorithm Motion Estimation Three step search and some method

是一个讲解fft的例子，内有程序的详细注解，很不错的demo，(fft learning process, very good demo, with detailed notes)

利用蝶形算法，实现快速傅立叶变换及其逆变换(The use of butterfly algorithm, fast Fourier transform and its inverse transform)

三步法哪l是一种较好的搜索算法，快速而且高效，它是在对数法的基础上对 其进行了改进，提出在每一步搜索后搜索步长均减半的算法。它基本保持了FS的 性能，但其计算量只有FS的10％左右。TSS在会议电视和可视电话中应用较多， 它通过三步搜索，逐步较小搜索步长。若最大搜索范围为士7，搜索精度取一个像 素，则步长为4、2、1，共需三步即可满足要求，从而得名。 (L three-step method which is a better search algorithm, fast and efficient, it is on the basis of the number of law be improved, made in every step of the search after the search step of the algorithm are reduced by half. It basically maintained the performance of FS, but the calculation is only about 10 of FS. TSS at the meeting on television and video telephony in the application of more three-step search through progressively smaller search step. If the maximum search range of disabilities 7, search for a pixel accuracy, the step size for the 4,2,1, a total of three steps to meet the requirements, thus its name.)

说明：  matlab 实现最短路径的DIJKSTRA算法，关于图论的(matlab DIJKSTRA algorithm to achieve the shortest path on graph theory)

matlab采集视频图像，背景检测，采集灰度图象等(matlab video image capture, background detection, acquisition and other gray image)

这是一个综合性的仿真程序。包括：用matlab生成一个FIR滤波器，得到滤波器系数及阶数；再用C语言产生一个混合频率的数字信号，之后将生成的数据样点送入到DSP主程序进行数字滤波，DSP主程序算法用的是循环缓冲区算法，这一部分在CCS上实现。(This is a comprehensive simulation program. Comprising: generating a matlab FIR filter, to obtain the filter coefficients and order then mixed to produce a C-frequency digital signal, and then the resulting data samples into the main program to the DSP for digital filtering, DSP main algorithm using a circular buffer algorithm, this part of the CCS to achieve.)

这是一个基于matlab另一种方法编写的梁的有限元程序，可以用于初学有限元程序的人参考。(this is a matlab program used for cantilever calculation, it can be used for a fresh hand to reference.)
