Aiming to meet the high-efficiency and high-reliability communication requirements of massive spiking neurons in neuromorphic computing chips, in-depth research has been carried out covering key technologies including spiking neuron signal encoding, on-chip network communication architecture, deadlock-free and congestion-aware on-chip network router design, as well as the toolchain for spiking neural […]
Overview In computer vision, deep learning has become a dominant approach for a broad range of applications, from autonomous driving to surveillance and security. Although deep neural networks have achieved remarkable success in solving complex tasks, research has shown that they are vulnerable to adversarial attacks. Such attacks typically involve […]
With the increasing adoption of structured-light and ToF sensing devices in smartphones, tablets, and other devices, the hardware foundation for 3D perception has gradually matured. The 3D market is expected to shift from an emphasis on imaging to an emphasis on perception. Perception, in turn, imposes higher requirements on the […]
The dataset is recorded by SmartToF camera model TC-E2, which acquires depth images with a resolution of 320×240 at a frame rate up to 60 fps. Besides, the TOF camera provides a field of view of 65°×38° in a standard lens. The maximum measurement range is 6 meters. The mechanical […]
RESEARCH BACKGROUND In the last decades, GNSS navigation has been much improved, compared to survey-grade equipment, low-cost devices performance is not satisfied market demands. Many particular scenarios such as offline shopping or open-air parking need high accuracy positioning. Because the raw GNSS data is unavailable, prior researchers can only […]
RESEARCH BACKGROUND The open access to GNSS raw measurements on Android smartphones is important for both the development of GNSS and smartphones, as we may experience higher accuracy LBS (Location Based Service) with lower cost devices in the future. Nowadays the ultra-low cost GNSS chipset in smartphone has the characteristics […]
