Abstract: The present specification discloses video matching. In a computer-implemented method, a plurality of feature vectors of a target video is obtained. A candidate video similar to the target video is retrieved from a video database based on the plurality of feature vectors of the target video. A time domain similarity matrix feature map is constructed between the target video and the candidate video based on the target video and the candidate video. Using the time domain similarity matrix feature map as an input into a deep learning detection model, a video segment matching the target video in the candidate video and a corresponding similarity is output.

Abstract: Disclosed are an integrated electronic cigarette and a processing method thereof. The integrated electronic cigarette includes a housing, and a main unit, a cartridge, and an auto-eject structure that are disposed within the housing, where the main unit and the cartridge are respectively disposed on both ends of the housing, and the auto-eject structure is located between the main unit and the cartridge. To smoke the electronic cigarette, a user inserts cartridge into a through hole defined in an end surface of the housing and presses the cartridge to return and secure the auto-eject structure at a preset position; the cartridge is thus coupled to the main unit and ready for inhaling. When replacing cartridge or adding e-liquid, the user presses cartridge to force auto-eject structure to eject from the preset position, and releases the force allowing cartridge to eject from the housing before the cartridge is simply pulled out.
