Abstract: A unified framework for detecting perception anomalies in autonomous driving systems is described. The perception anomaly detection framework takes an input image from a camera in or on a vehicle and identifies anomalies as belonging to one of three categories. Lens anomalies are associated with poor sensor conditions, such as water, dirt, or overexposure. Environment anomalies are associated with unfamiliar changes to an environment. Finally, object anomalies are associated with unknown objects. After perception anomalies are detected, the results are sent downstream to cause a behavior change of the vehicle.

Abstract: Techniques are described for performing an image processing on frames of a camera located on or in a vehicle. An example technique includes receiving, by a computer located in a vehicle, a first image and a second image from a camera; determining a first set of characteristics about a first set of pixels in the first image and a second set of characteristics about a second set of pixels in the second image; obtaining a motion information for each pixel in the second set by comparing the second set of characteristics with the first set of characteristics; generating, using the motion information for each pixel in the second set, a combined set of characteristics; determining attributes of a road using at least some of the combined set of characteristics; and causing the vehicle to perform a driving related operation in response to the determining the attributes of the road.

Abstract: The present disclosure provides a binding agent for graphene film transfer, comprising 5-95 parts by weight of a volatile organic solvent A and 95-5 parts by weight of a volatile organic solvent B. The present disclosure does not use a transition substrate, which greatly reduces the cost, and realizes low-cost transfer. Moreover, the binding agent can be completely volatilized, so that the transferred graphene has no residual glue. The graphene is pure and pollution-free, and a high-quality graphene film can be obtained after the transfer of the graphene. Furthermore, high-quality multi-layer transfer can be achieved and the quality of multi-layer graphene can be guaranteed. Moreover, the graphene can be transferred to any different target substrates.
