用m序列过低通滤波器模拟产生带限高斯白噪声，m序列的长度足够长时功率谱特性接近高斯白噪声的特性。(M-sequence low-pass filter with analog band-limited white Gaussian noise generated, m length of the sequence is long enough the power spectral characteristics close to Gaussian white noise characteristics.)

用OpenCV实现的Matlab中形态学细化、提取骨架、收缩算法。测试效果与Matlab相同。(Algorithms of morphological thinning,Skeleton and Shrink,ported from Matlab to OpenCV.)

BACKPROJ uses the filtered or unfiltered backprojection algorithm to perform the inverse Radon transform. The filter is designed directly in the frequency domain and then multiplied by the FFT of the projections. The projections are zero-padded to a power of 2 before filtering to prevent spatial domain aliasing and to speed up the FFT.
