Abstract

Embodiments of this application disclose a target tracking method performed at an electronic device. The electronic device obtains a first video stream and detects candidate regions within a current video frame in the first video stream. The electronic device then extracts, from the candidate regions, a deep feature corresponding to each candidate region and calculates a feature similarity for each candidate region and a deep feature of a target detected in a previous video frame. Finally, the electronic device determines, based on the feature similarity corresponding to the candidate region, that the target is detected in the current video frame. Target detection is performed in a range of video frames by using a target detection model, and target tracking is performed based on the deep feature, so that occurrence of cases such as a target tracking drift or loss can be effectively prevented, to ensure the accuracy of target tracking.

Abstract

In a service data processing method performed by a server, user speech information collected by a first terminal is received. A target service operation code according to the user speech information is obtained. The target service operation code is used for identifying target service operation information. The target service operation code is transmitted from the server to the first terminal, so that the first terminal plays the target service operation code by using a speech. The target service operation code obtained by a second terminal is received. A target execution page corresponding to the target service operation code is searched for. The target execution page is transmitted to the second terminal, so that the second terminal executes a service operation corresponding to the target

Abstract

Aspects of the disclosure provide a method for reducing operational complexity of mobile gaming. A scene switching instruction is received via an application interface. The application interface displays a first scene including a to-be-teleported operation object. The first scene displayed on the application interface is switched to a second scene according to the scene switching instruction. The second scene includes a target teleportation location object. A touch operation on the target teleportation location object in the second scene is received. In response to receiving the touch operation, a process of updating a coordinate of the to-be-teleported operation object to a coordinate of the target teleportation location object in the second scene is performed.

Abstract

In a method for determining a coding cost of a coding unit (CU) that is performed by a server, a CU subject to predictive coding in an intra-frame prediction mode is determined. Pixel gradient information corresponding to the CU is performed. A division predecision on the CU is made according to the pixel gradient information. A first coding cost is determined as a second coding cost of the CU in a case that a result of the division predecision on the CU is negative. The second CU is used for determining a division policy of a coding tree unit (CTU) corresponding to the CU, and the first coding cost is a coding cost obtained by performing predictive coding on the CU by using a current size of the CU as a size of a prediction unit (PU).
