a Implementation of Gaussian, Laplacian, Inverse operators in the MAPbI3/Bi2O2Se heterotransistor array for the image processing of noise reduction, edge detection, and image stylization, respectively. b Scheme of integrating the MAPbI3/Bi2O2Se heterotransistor array with the YOLOv4 network for the traffic-light detection task under dim-light conditions. c Recall–precision curves of green, red, and yellow traffic lights preprocessed by the heterotransistor array under dim-light conditions. d Mean average precisions (mAP) of the raw and the preprocessed images for green, red, and yellow traffic lights.
