1) rotation sampling
轮换抽样
2) nonsubsampled complex contourlet transform(NSCCT)
非抽样复轮廓波变换(NSCCT)
1.
A novel nonsubsampled complex contourlet transform(NSCCT)is constructed by combining the two dimensional dual-tree complex wavelet transform(DT-CWT)and nonsubsampled directional filter bank(NSDFB).
将二维双树复小波变换(DT-CWT)与非抽样方向滤波器组(NSDFB)相结合,构造一种新的非抽样复轮廓波变换(NSCCT),并对其平移不变性作了相应证明。
3) transform sampling
变换抽样
1.
The transform sampling method is used for processing uniformly distributed random sequences,and then a pair of independent Gaussian distributed sequences are generated in real-time.
运用变换抽样法处理均匀分布随机序列,实时产生一对独立的高斯噪声序列,处理过程中用到的对数、开方、三角函数等超越代数计算利用CORD IC算法,构建运算功能单元在超大规模集成电路上实现。
4) rotation sampling
