Method for determining image similarity, video scene switching recognition method and device

Abstract

An embodiment of the present invention provides a method for determining image similarity, a video scene switching recognition method and device, wherein the method for determining image similarity includes: the first feature point of the current frame image in the acquired video data Set, and the feature points that match the second feature point set of the comparison frame image, as the associated feature point pair set; obtain the preset similarity of the feature points that do not match between the first feature point set and the second feature point set degree; based on the total number of associated feature point pairs and the Euclidean distance of associated feature point pairs, calculate the similarity of associated feature point pairs; the similarity of associated feature point pairs is positively correlated with the number of associated feature point pairs, It is negatively correlated with the Euclidean distance of the associated feature point pair set; the weighted average of the preset similarity and the similarity of the associated feature point pair set is determined as the global feature similarity between the current frame image and the comparison frame image.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a method for determining image similarity, a video scene switching recognition method and a device. Background technique [0002] With the development of multimedia information data, in the production process of video data such as film and television dramas, video clips from different camera angles of different scenes will be combined, and different lens languages ​​will be used to express different emotions and convey various relationships. In the production process, it is often necessary to segment video clips of different scenes and configure different color restoration parameters for video clips of different scenes. For example, in the restoration project of old movies, it is necessary to configure different color restoration for video clips of different scenes parameters, so that the scene switching of the video needs to be identified. [0003] The method for deter...
