(EN) A picture selection method and related equipment
(ZH) 一种图片选择方法及相关设备
Abstract
(EN)
The embodiment of the invention discloses a picture selection method and related equipment. The method comprises the steps that feature information of each picture in M pictures on a time sequence isacquired, and the feature information is used for describing display content of the corresponding picture; According to the feature information of each picture in the M pictures, interframe information of the M pictures on the time sequence is determined, and the interframe information represents the mutual relation and/or change condition of the feature information on the time sequence; feature change key points are determined according to the inter-frame information, Wherein when the mutual relation meets a first preset threshold value and/or the change condition meets a second preset threshold value, the current frame time point corresponding to the mutual relation and/or the change condition is used as a feature change key point, and the time point is a point on the time sequence; AndN pictures corresponding to the feature change key points are selected from the M pictures, and the N pictures are played and displayed. According to the embodiment of the invention, the accuracy of picture selection and the distinction degree of pictures can be improved.
