用直接解得办法求摄影测量中的相对定向元素( use direct measurement to find the relative orientation elements in photography)

该程序功能主要是运用matlab的小波函数完成图像的读入和显示，并实现加入噪声，最后运用小波函数滤除(The main function of the program is to use matlab image of the wavelet function of the read and display, and the realization of adding noise, and finally the use of wavelet function filter)

说明：  学习使用matlab数学建模，包括了一些基本教程和经典的建模例子。(Learning to use matlab mathematical modeling, including some basic courses and classic modeling examples.)

说明：  最优制导律攻击机动目标弹道仿真，matlab编写。(Optimal guidance law for maneuvering target trajectory simulation attacks, matlab prepared.)

声音采集处理，涉及频率，变换等，属于入门级别程序(Sound acquisition and processing, involving frequency, transform, are entry-level program)

小波变换的相关matlab代码，实验中均附有所需图片，直接运行可以显示(wavelet transformation)
