本文基于BP神经网络应用于预测的原理，提出预测步骤及预测可行性，探讨建立基于BP神经网络的预测模型的关键技术，包括样本的选取与预处理、输入输出变量的选取、隐层节点数的确定、初始权值和阈值的选取、激活函数、训练算法与参数的选取，最后建立合理的网络模型；结合住宅市场的实际情况，建立两类BP 神经网络预测模型：基于时间序列的趋势预测模型以及基于影响因素的回归预测模型，即分别采用神经网络趋势预测和回归预测的思路，把住宅市场的供给、需求与房价的历年数据以及其影响因素的数据分别作为学习样本，建立预测模型，进行预测。(Real estate development risk prediction )

产生调频步进信号，再进行脉冲压缩，混频，最后进行高分辨率成像。本程序用于测距，参数可以进行修改。注释详细。(stepped LFM generating, and then pulse compression, mixing, and finally high-resolution imaging. The procedure used for ranging, the parameters can be modified. Detailed notes.)

An extra file fdct_usfft_path.m is included in fdct_usfft_matlab directory. This script needs to be called to append several subdirectories into the searching path.

该方法能较快实现数字图像相关方法计算位移和应变(The realization of digital image correlation method to calculate the displacement and strain )

This code is used to detect corners in the image,contains harris,susan,gilles,harrislaplace,youhua and so on. This code is ease to understand and can be used convinently. It will be useful for some people who are interested in this domain. Happy every one!
