Intelligent k-means

matlap程序设计　刘卫国版　课后实验6(matlap Liu Weiguo version of Experiment 6)

该程序是在flac下运行的，没找到flac，所以用matlab表示了，供岩土力学研究方向学习(The program is run under flac, did not find flac, so use matlab shows for rock mechanics research study)

中国人口数据测算，基于生命表对中国人口数据进行测算的matlab程序(China' s population data, based on life table estimates of China' s population data matlab program)

Thresholding is used to segment an image by setting all pixels whose intensity values are above a threshold to a foreground value and all the remaining pixels to a background value. Whereas the conventional thresholding operator uses a global threshold for all pixels, adaptive thresholding changes the threshold dynamically over the image. This more sophisticated version of thresholding can accommodate changing lighting conditions in the image, e.g. those occurring as a result of a strong illumination gradient or shadows.

BIOMETRICS SOLUTIONS USING DATA AND IMAGES MATHEMATICS FORMS

说明：  海浪谱matlab的仿真程序,在不同风速下对PM海浪谱进行仿真。(Wave spectrum matlab simulation program, the PM under different wind wave spectrum simulation.)

小波的matlab实现，Harr小波分解，Harr小波重构，如果需要压缩80%，则对分解后的系数及 按照绝对值大小进行排序，保留其中占20%绝对值相对较大的系数，然后按照信号重构方法对保留的系数进行重构，这样就可完成压缩。

改进的基于区域的图像分割算法，对含有噪声的图像非常适用！在matlab6.5下顺利编译通过 (Improvement on the region's image segmentation algorithm for noisy images very well! In matlab6.5 smoothly through the compiler)
