贝叶斯决策包含最小风险和最小错误概率两种情况的仿真(Bayesian decision-making included the minimum risk and minimum error probability of the two simulation)

The matlab source code for the paper "A Partial Intensity Invariant Feature Descriptor for Multimodal Retinal Image Registration". This paper has been accepted by IEEE Transaction on Biomedical Engineering.

这是一个粒子群优化算法的博士毕业论文，适合做毕设，希望对大家有用(This is a PSO Ph.D. thesis, suitable for complete set, we want to be useful)

多径效应的时域表示实际上就是不同路径来的信号存在随机的时延差。对于抗其它扩频信号干扰性能，及抗多址干扰性能。我们这里考虑简单的情况，只考虑一个用户干扰的情况，说明其具有抗多址干扰性能就行。(Multipath effect is actually a time domain representation of the signal path to the existence of different random time delay difference. Other spread spectrum signal for the anti-interference performance, and anti-MAI performance. Here we consider the simplest case, considering only one user interference, indicating its performance with anti-multiple access interference on the line.)

Designs a linear phase FIR lowpass filter such that it: - minimizes the filter order - has a constraint on the maximum passband ripple - has a constraint on the maximum stopband attenuation (This is a quasiconvex problem and can be solved using a bisection. minimize filter order n s.t. 1/delta <= H(w) <= delta for w in the passband |H(w)| <= atten_level for w in the stopband where H is the frequency response function and variable is the filter impulse response h (and its order/length). Data is delta (max passband ripple) and atten_level (max stopband attenuation level). )

This code is used to create input files for the 2D FEM solver used in ME 413 course. It uses the freely available mesh2d mesh generator to create the mesh.
