针对应用于图像分割的自适应正交投影分解方法的具体算法的实现问题，提出了一种基于两阶段搜索的实现算法。

In this paper, a two-stage search fast algorithm for adaptive projective decomposition, which is used in image segmentation, is presented.

正交投影（OP）自适应波束形成算法性能优良，但需要进行复协方差矩阵特征分解，运算量大。

The orthogonal projection (OP) adaptive beamforming algorithm has good performance but it is computationally expensive because of performing eigen-decomposition of the complex covariance matrix.

本文提出了一种基于正交投影算法的部分自适应方法。

A partially adaptive approach based on orthogonal projection was proposed in this paper.
