GISA
提出了一种广义迭代收缩算法(GISA)非凸稀疏编码,可以解决稀疏编码的一些优化问题.希望能对大家有所帮助!(A generalized iterative contraction algorithm (GISA) is proposed to solve some of the optimization problems of sparse coding. We hope to be helpful to everyone!)

三次B样条曲线拟合算法
B样条曲线分为近似拟合和插值拟合,所谓近似拟合就是不过特征点,而插值拟合就是通过特征点,但是插值拟合需要经过反算得到控制点再拟合出过特征点的B样条曲线方程。这里会一次介绍两种拟合算法。

傅里叶谱与频域低通滤波
说明: 傅里叶谱与频域低通滤波 (a)从图书网站下载图4.41(a)并计算其(居中)傅里叶谱。(b)显示频谱。(c)在等式(4.8-7)中实现高斯低通滤波器。您必须能够指定结果2D函数的大小,M x N。此外,您必须能够指定高斯函数的中心位置。(d)从图书网站下载图4.41(a),并对其进行低通滤波,以复制图4.48中的结果。(Fourier Spectrum and Lowpass Filtering in Frequency Domain
(a) Download Fig. 4.41(a) from the book web site and compute its (centered) Fourier spectrum.
(b) Display the spectrum.
(c) Implement the Gaussian lowpass filter in Eq. (4.8-7). You must be able to specify the size, M x N, of the resulting 2D function. In addition, you must be able to specify the location of the center of the Gaussian function.
(d) Download Fig. 4.41(a) from the book web site and lowpass filter it to duplicate the results in Fig. 4.48.)
