Abstract: An eye state detection method, including: acquiring a target image (101); positioning a plurality of eye feature points in the target image to determine position coordinates of the plurality of eye feature points (102); normalizing the position coordinates of the plurality of eye feature points to obtain normalized position feature data (103); and determining an eye state in the target image based on the position feature data (104). An eye state detection apparatus, a device and a medium are also provided.

Abstract: The present application provides a gesture recognition method, a device, an apparatus and a storage medium. The gesture recognition method includes: acquiring coordinates of a center point of a gesture in an ith frame of image; determining whether the center point of the gesture in the ith frame of image is within a preset region; if yes, determining that coordinates of an actual center point of the gesture in the ith frame of image are coordinates of an actual center point of the gesture in the (i−1)th frame of image; wherein i is an integer greater than or equal to 2, and the preset region is a region taking the actual center point of the gesture in the (i−1)th frame of image as a center; and performing a dynamic-gesture recognition according to coordinates of an actual center point of the gesture in each frame of image.

Abstract: A voice question and answer method and device, a computer readable storage medium, and an electronic device are described. The method comprises: receiving question voice information, and obtaining question text information according to the question voice information; performing at least one of general semantic analysis processing and dedicated semantic analysis processing on the question text information to generate an analysis result; and obtaining answer information according to the analysis result. The general semantic analysis is used for semantic analysis in the general field, and the dedicated semantic analysis is used for semantic analysis in the art field.

Abstract: A fingertip detection method, a fingertip detection device and a storage medium are disclosed. The fingertip detection method includes: determining a minimum-depth point in a hand area to be detected based on a depth image; determining a hand vertex in the hand area to be detected based on the depth image; determining a fingertip position based on the minimum-depth point and the hand vertex.
