查询词典 PGA

Some key computing components abstracted from the algorithm,such as CORDIC processor,complex vector correlator and prominent scatter filter are also discussed.

实验结果表明，改进的算法较经典的PGA算法明显地减少了迭代次数，在SOC中通过硬件的运算精度能够满足系统的要求。

The robust method, which improves the GVF and optimizes search by PGA, is proposed to extract contour veraciously in this section. Due to the information exchange between adjoining points by chromosome crossover, the points are driven to optimization positions in the fined-grained model.

因此，本文通过改进GVF Snakes梯度矢量流，并引入遗传优化搜索，提出了一种稳健的目标提取与跟踪算法：即对于收敛于局部极值处的轮廓控制点，利用细粒度遗传算法，将相邻的处于全局最优控制点的信息通过染色体遗传操作传递给这些点，并驱使它们向全局最优处运动。
