Abstract: A compilation method includes obtaining a source program code. The source program code includes a first function in a first language code and a second function in a second language code. The first language code is a native language. The second language code is a non-native language. The method also includes generating a third language code based on the source program code. The third language code includes a third function, a fourth function and a fifth function. The third function is generated based on the first function. The fourth function is generated based on the second function. The fifth function is generated based on the first function and the second function. Executing the third function invokes the fourth function via the fifth function.

Abstract: An electronic device obtains N frames of images, and then obtains a first operation performed by a user on a target object on a screen. The electronic device displays a target box whose area cyclically changes, obtains information about the target box in an Nth frame of image based on a second operation performed by the user on the target object, and determines a feature vector of the target object based on the information about the target box.
