边缘检测，源代码，基于matlab的。是canny算子。也可以改动一下模板，即可变成其他算法的了。(Edge detection, source code, based on matlab' s. Is a canny operator. Can also change what the template, you can become the other algorithms.)

A 10th order FIR system, excited by a sum of 5 sinusoids. Assume any numeric values for system coefficients and input signal parameters. The output of the system is corrupted by Gaussian observation noise with zero mean and variance 2 σ v (consider 2 σ v = 0.1 and 1). The estimator has access to the input and noise corrupted output of the system. However, the estimator has no knowledge about the system order, its coefficient values and observation noise variance.
