We demonstrated the use of the analog self electro-optic effect device (SEED) as part of an artificial retina chip for the detection and estimation of local motion. The characterization was performed by comparing our chip to biological and computational models and to other artificial retina chips. Its main unique feature is the optical output, since most chips have electrical output. By combining the response of the chip with temporal information about the input image, it is possible to estimate the velocity perpendicular to an edge, including its direction.
我们展示了模拟自电光效应器件（SEED）作为人工视网膜芯片的一部分用于局部运动检测和估计的应用。通过将我们的芯片与生物模型、计算模型以及其他人工视网膜芯片进行比较来进行特性描述。其主要独特之处在于光学输出，因为大多数芯片具有电输出。通过将芯片的响应与关于输入图像的时间信息相结合，就有可能估计垂直于边缘的速度，包括其方向。
