Description: Matching Pursuit 算法是信号分解的一种具体实现方法。但其本质上则是一种估计
信号模型参数的方法，因而可直接用于信号检测及参量估计。本文以谐波信号特征参量的估计为例，介绍了其具体实现方法。-Matching Pursuit algorithm is a specific method of signal decomposition. But by its very nature is an estimated signal model parameters, and thus can be directly used for signal detection and parameter estimation. In this paper the harmonic signal characteristics of the estimates of the parameters, for example, describes the specific implementation method. Platform: |

Description: The problem of optimal approximation of members
of a vector space by a linear combination of members
of a large overcomplete library of vectors is of importance
in many areas including image and video coding,
image analysis, control theory, and statistics. Finding
the optimal solution in the general case is mathematically
intractable. Matching pursuit, and its orthogonal
version, provide greedy solutions to this problem.
Orthogonal matching pursuit typically provides significantly
better solution compared to the nonorthogonal
version, but requires much more computation. This
paper presents a fast algorithm for implementation of
orthogonal matching pursuit which for many coding
applications has computational complexity very close
to that of the nonorthogonal version. Platform: |
