Single-pixel fast-moving object classification based on optical-electronical hybrid neural network (Invited

  • 摘要: 对快速运动物体进行持续分类具有重要的应用前景。受限于有限的数据传输带宽和存储空间,目前基于场景图像的物体分类技术难以实现对运动物体的持续分类。受到单像素成像在时间上累积获取信息这一方式的启发,结合深度学习,提出了一种基于光电混合神经网络的单像素快速运动物体分类方法。该方法不需要获取目标物体的图像,利用对光场的空间调制和单像素测量,直接获取用于分类的特征信息,从而避免了在持续分类过程中基于图像分类方法产生的海量图像数据。单像素测量过程作为神经网络的一部分,将光计算与电子计算无缝衔接起来,构建了一个光电混合神经网络用于对物体的分类。通过对快速旋转圆盘上的手写数字进行持续分类实验测试,证明了提出的方法在分类快速运动的手写数字方面的能力,超过了人眼视觉。

     

    Abstract: Successive classification of fast-moving objects is significant in various fields. However, due to the limited data transmission bandwidth and data storage space, it is challenging to perform fast-moving object classification based on scene photography for a long duration. Inspired by single-pixel imaging and combined with deep learning, a single-pixel fast-moving object classification method based on optical-electronic hybrid neural network was proposed. The proposed method had no need to acquire the images of objects, but obtained the feature information for classification directly by using spatial light modulating and single-pixel detecting. Thus, the massive image data produced by the image-based classification for a long duration was avoided. As part of the neural network, the single-pixel detecting connected optical computing and electronic computing seamlessly, an optical-electronic hybrid neural network for object classification was constructed. The proposed method in classifying fast-moving handwritten digits on a rotating disk was experimentally demonstrated, which passed through the field of view successively. The experiment confirmed that the classification ability of the proposed method had exceeded human vision.
