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.

Abstract: An image parsing method includes obtaining feature information of an initial image, parsing first feature information in the feature information using a first channel to obtain a first prediction result, parsing second feature information in the feature information using a second channel to obtain a second prediction result, where a size of the first feature information meets a first size range, a size of the second feature information meets a second size range, and the first size range is less than the second size range, and outputting the first prediction result and the second prediction result as a parsing result of the initial image.

Abstract: A method for selecting an image based on burst shooting is provided, which relates to the field of terminal technologies. The method includes: an electronic device displays a preview interface; detects a first operation used to start burst shooting; obtains N images; then performs scene recognition based on K images that meet an image quality screening condition, to determine a shooting scene; and finally determines M images based on the shooting scene, where N is greater than or equal to K, N is greater than or equal to M, N and K are positive integers greater than 1, and M is a positive integer greater than or equal to 1. This technical solution helps improve quality of an image obtained by the electronic device through screening, thereby improving user satisfaction with an image that is automatically obtained through screening during burst shooting by the electronic device.

Abstract: Embodiments of this application provide a volume adjustment method and an electronic device. The volume adjustment method includes: receiving target volume used when a media playing device plays content; obtaining an audio signal, where the audio signal includes a first signal and a second signal, the first signal is a sound signal that is collected by a wearable device worn by a user and that is generated when the media playing device plays the content, and the second signal is a noise signal collected by the wearable device; determining adjusted volume based on the audio signal and the target volume; and sending the adjusted volume to a target device through a communication connection to the target device, where the adjusted volume is used to update volume used when the media playing device plays the content.
