Abstract: This application discloses an image processing method. The method includes: obtaining to-be-rendered data; performing rasterization processing on the to-be-rendered data to obtain a first image; and identifying a target object in the first image by using an identifier, and performing ray tracing processing on the target object to obtain a second image. Because ray tracing processing is performed on a local object in an image, computing power requirement for image rendering is reduced, so that an electronic device with limited computing power can also implement image rendering by using the ray tracing processing, to improve image rendering effect.

Abstract: An artificial intelligence-based semantic recognition method, apparatus, and device. In the artificial intelligence-based semantic recognition method, a pre-trained semantic recognition model is trained by using a training corpus configured by a developer on a model training platform such as a Bot platform and a negative corpus provided on the model training platform, where the negative corpus is extracted by mapping an encoding value of the training corpus to a negative corpus set. Therefore, the negative corpus is extracted based on the encoding value of the training corpus, and a randomized method for generating the negative corpus is changed into a stable method.

Abstract: The present disclosure relates to screen projection methods and electronic devices. One example method is applied to a first electronic device. The first electronic device includes a first display screen. The first electronic device displays a first interface on the first display screen. The first electronic device receives a first operation of projection to a second electronic device. The first electronic device sends, in response to the first operation, the first interface obtained after a display style is adjusted to the second electronic device, where the first interface obtained after the display style is adjusted is determined based on display screen information of a second display screen of the second electronic device.
