Abstract

The invention discloses a video positioning method, device and electronic equipment. Wherein, the method includes: acquiring video and sentences; performing feature extraction on the video and the sentence respectively to obtain corresponding video segment features and word features; fusing the video segment features and the word features to obtain fusion features ; Aggregating and associating the fusion feature layer by layer based on time series through a time series convolutional neural network to obtain a multi-layer time series convolution feature map; performing semantic modulation on each layer feature map in the multi-layer time series convolution feature map to obtain modulation After the feature map, and perform temporal convolution operation on the modulated feature map to obtain the target video segment related to the semantics of the sentence. Through the present invention, it is possible to quickly and accurately locate the target video segment related to the semantics of the input sentence.

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...
