肺实质提取
本段代码用来进行肺实质的粗提取,为病灶提取做准备。首先对原始dcm图片进行预处理,随后使用大津法对图像进行阈值分割,得到二值图,随后,使用较为简单的小面积法删除背景区域,取反进行掩模,最后通过掩模与原图像的运算,将肺实质完整的提取出来。

Leaflet_WCDMAchannels
the comb pilot aided channel estimation in ofdm modulation is considered. the power of pilot subchannels is under the control.
The data experience frequency selective channel then the AWGN noise is added to make the situation worse. The bit error rate is ploted versus SNR.

PBGBand
光子晶体的能带图计算,其实质就是电磁本征值(复矢量场)的问题。利用平面波展开磁场,引入f(r)=1/eps(r),再利用倒格矢G将f(r)展开,将两者代入光子晶体的支配方程,最后得到一个平面波展开的方法的线性方程组,最终转化为求解其特征值向量的问题。(Energy band diagram of the photonic crystal, its essence is the electromagnetic eigenvalues (complex vector field).The linear plane wave expansion magnetic field, the introduction of f (r) = 1/eps (r), re-use reciprocal lattice vector G will expand f (r), the two substituted into the governing equations of the photonic crystal, and finally get a plane wave expansionequations, and ultimately into solving the problem of its eigenvalues .)
