Firstly, the row crop and background were segmented by the excess green value. Secondly, the image strips were divided by crop image horizontally and the position was calculated by detecting the peak on the curve resulting from vertical projection of strips. Finally, the crop rows center lines were accomplished by robust regression.

This could be explained by parallel processing. And the type of configurations had almost no effect on the number of fixations and the distance of the first saccade from the target and the probabilities of iniatial fixation landed on the target.

该机制在眼动指标上表现为：找到目标所需的注视点个数、首注视点与目标位置的距离以及首注视点为目标位置的可能性不受干扰子空间布局的影响。

And Fewer fixations were required to find the target in the repeated configurations than in the new configurations. Furthermore, the distance of the first saccade from the target were smaller for the repeated than for the new displays. In addition, the probabilities of initial fixation landed on the target were greater for the repeated than for the new contexts.

该机制在眼动指标上表现为：干扰子的空间布局固定时，与空间布局变化时相比，找到目标所需的注视点个数更少、首注视点与目标位置的距离更近以及首注视点更可能落在目标位置。

Based on accurate step motor system parameters, the state equations describing step motor dynamic characteristics are set up. The operation of the self synchronization closed loop control system is simulated on computer. In the research the principle analysis and system design have been done about self synchronization closed loop operation.

本研究获得以下主要结论：(1)短SOA下，无论是3-D还是2-D，非预测性边缘位置线索对后续辨认任务均发生了启动效应。3-D空间中边缘位置线索提示诱发了注意的自动定向，注意从一个深度面转移到另一深度面需要耗费一定的时间。3-D空间中产生的经典注意提示效应，在ERP上表现为有效提示下P1、N1、N2等早成分的增强；跨深度空间启动效应主要应由N1的增强效应加以解释。
