Abstract: Implementations of the present disclosure provide a solution for object detection. In this solution, object distribution information and performance metrics are obtained. The object distribution information indicates a size distribution of detected objects in a set of historical images captured by a camera. The performance metric indicates corresponding performance levels of a set of predetermined object detection models. At least one detection plan is further generated based on the object distribution information and the performance metric. The at least one detection plan indicates which of the set of predetermined object detection models is to be applied to each of at least one sub-image in a target image to be captured by the camera. Additionally, the at least one detection plan is provided for object detection on the target image. In this way, a balance between the detection latency and the detection accuracy may be improved.

Abstract: A method includes: obtaining a signal strength sequence of signals detected by a user terminal during a travel route. The detected signals are originated from signal sources disposed at different locations in the travel route, and the different location includes one or more vehicles or one or more stops. The method further includes: extracting, from the signal strength sequence, a first sequence fragment corresponding to a signal transmitted by a signal source disposed at a vehicle; determining a travel time duration of the user riding on the vehicle according to a signal strength value and time stamp information of the first sequence fragment.

Abstract: This disclosure relates to network configuration using multicast address modulation. In one aspect, a method includes dividing data for completing network configuration of a device. Multiple packets are selected from the divided data. A total length of data in the multiple packets is obtained. Multicast address modulation is performed on indexes of the multiple packets to obtain a multicast target address. Data in the multiple packets is parsed based on the total length of the data in the multiple packets and the multicast target address.
