我们提出了一种基于低等动物视觉系统的模拟网络，用于通过简单形状识别来检测接近物体的运动。蝗虫可以通过在其大脑中存在的下降对侧运动检测器（DCMD）中执行一个简单的过程来检测接近的物体，该检测器感知碰撞前投射在视网膜上的图像的尺寸和扩张速度的增加。响应对应于接近的速度和方向。青蛙可以根据视网膜信息，通过在大脑中存在的顶盖和丘脑中执行简单的过程来识别简单的形状；这称为 Ewert von Seelen 模型。所提出的网络是用简单的模拟金属氧化物半导体（MOS）电路构建的。具有集成电路重点的仿真程序（SPICE）的仿真结果表明，该网络能够检测接近的速度和方向，并且还可以识别圆形、正方形、三角形和矩形等简单形状。
We proposed an analog network for motion detection of an approaching object with simple-shape recognition based on the visual systems of lower animals. Locusts can detect an approaching object by performing a simple process in a descending contralateral motion detector (DCMD) existing in their brain, which senses the increase in size and expansion velocity of the image projected on a retina just before collision. The responses correspond to the approaching velocity and direction. Frogs can recognize a simple shape by performing a simple process in a tectum and thalamus existing in their brain based on retinal information; this is called the Ewert von Seelen model. The proposed network was constructed with simple analog metal-oxide-semiconductor (MOS) circuits. Simulation results with a simulation program with integrated circuit emphasis (SPICE) showed that the network was able to detect the approaching velocity and direction, and also recognized simple shapes such as a circle, square, triangle and rectangle.
