说明：  EM算法实现，对于需要的朋友来说还不错的，(EM algorithm, for a friend in need is also good,)

This demo tracks cars in a video by detecting motion using optical flow. The cars are segmented from the background by thresholding the motion vector magnitudes. Then, blob analysis is used to identify the cars.

用FFT计算信号的功率谱密度时，需要先计算FFT，再计算双边谱密度，然后计算单边谱密度。在matlab里注意FFt要除以采样点数，计算双边谱时要注意除以频率分辨率。 ( When calculated using the FFT power spectrum density signal, you need to calculate the FFT, and then calculate the bilateral spectral density, and then calculate the unilateral spectral density. In matlab in Note FFt divided by sampling points should be noted when calculating the bilateral spectrum divided by the frequency resolution.)

数学建模，matlab实现主成分分析法，以及直方图绘制( Mathematical modeling, matlab principal component analysis, and the histogram drawing )

these are some matlab programs 1.additon of two images 2.converv mat to gray 3.addition of two images

一个高效的matlab代码，用来拟合图像中的圆(An efficient matlab code used to fit the image of a round)

Written for engineering and computer science students and practicing engineers, this book provides the fundamental applications and mathematical techniques of signal processing. Topics covered include programming in MATLAB, filters, networking, and parallel processing. MATLAB is introduced and used to solve numerous examples in the book. Companion software available In addition, a set of MATLAB M-files is available on a CD bound in the book.

hmm hidden markov model nice pretty code good luck!!!

Calculate the lyapunov index toolbox. Contains a variety of methods, can be directly run.

matlab 自动生成各种随机数的命令，希望对大家有所帮助(hehe ，it is very useful to us.I hope it can give everyone a help.)
