我课设编写的一个重构算法--子空间追踪方法代码

Spectrum sensing using FFT Averaging Ratio (FAR) Algorithm

This block filters each channel of the input signal independently over time. The output frame status and dimensions are always the same as those of the input signal that is filtered. When inputs are frame based, the block treats each column as an independent channel the block filters each column. When inputs are sample based, the block treats each element of the input as an individual channel.

傅里叶变换的函数文件，可直接调用，可以直接显示幅频和相频曲线(Fourier transform function file, can be called directly)

本例中使用harris的方法实现角点检测 计算机视觉中常用的图像特征包括：点、边缘、直线、曲线等，其中，点特征属于局部特征，对遮挡有一定鲁棒性。图像中点特征数量多，提取速度快，并且容易辨识区分，因此在图像处理中占有重要地位。在角点处，图像上的一个小窗口沿任何方向移动，窗口内的图像都有明显的灰度变化，因此角点是好的点特征。
