新的检测函数如下,$latex P$是一个$latex D\times C$的矩阵,每一行代表一个维度的特征对应的C个滤波器的线性组合稀疏,$latex P$是一个稀疏,需要在第一帧中进行学习,之后跟踪中保持不变就可以了。 跟踪的目标函数如下所示,这个新的目标函数加入了对$latex P$的正则化, 下面就是Guss-Newton法来解最优化...
This algorithm is asymptotically O(n log n), but the constants that are hidden in the O notation are quite large. In this paper we present an inversion algorithm for the pseudo-polar Fourier transform (PPFT) that is based on expressing its Gram operator as a convolution filter. This filter...
