Abstract

The invention discloses a video positioning method and device and electronic equipment. The method comprises the steps of obtaining a video and a statement; performing feature extraction on the videoand the statement respectively to obtain corresponding video clip features and word features; fusing the video clip features and the word features to obtain fusion features; aggregating and associating the fusion features layer by layer based on a time sequence through a time sequence convolutional neural network to obtain a multi-layer time sequence convolutional feature map; and performing semantic modulation on each layer of feature map in the multi-layer time sequence convolution feature map to obtain a modulated feature map, and performing time sequence convolution operation on the modulated feature map to obtain a target video clip related to semantics of the statement. According to the method and the device, the target video clip related to semanteme of the input statement can be quickly and accurately positioned.

Description

technical field [0001] The present invention relates to computer vision technology in the field of artificial intelligence (AI, Artificial Intelligence), in particular to a video positioning method, device and electronic equipment. Background technique [0002] Computer vision technology is a branch in the field of AI technology. Its purpose is to use machines to learn based on prior knowledge, so as to have the logical ability to classify and judge media information such as videos and images. [0003] Video localization technology is a typical application of computer vision technology. For a given sentence, video localization technology can find video clips semantically related to the sentence from the video. For example, for the sentence "I want to go swimming", the video positioning technology can find a video segment including a swimming scene from the video. For another example, the video positioning technology can be applied to application scenarios such as online vid...
