Problems solved by technology

Selecting an image with the best quality from the entire cycle of a person's appearance to disappearance for subsequent structured analysis can undoubtedly improve the accuracy of the analysis, but if the cycle is very long, this strategy will greatly limit the analysis speed

Abstract

The invention relates to the technical field of video analysis, and provides a target image screening method and device, and the method comprises the steps: obtaining at least one frame of to-be-processed image; grouping the target images to obtain one or more target image groups; scoring the quality of the target image by using the scoring model to obtain a model score of the target image; performing scoring according to the geometrical characteristics to obtain a geometrical characteristic score of the target image; obtaining a score of the target image according to the model score and the geometric characteristic score of the target image; and according to the score, screening out a target image meeting the requirement from the target image group for target retrieval, target identification or target attribute analysis. The method provides a more objective and accurate standard for quality evaluation of the target image.

Description

Technical field [0001] The present invention generally relates to the technical field of video structured analysis, and particularly relates to a target image screening method and a target image screening device. Background technique [0002] When performing video structure analysis such as target retrieval, target recognition, or target attribute analysis, in order to improve the accuracy of retrieval, recognition, and attribute analysis, it is hoped to select the best quality target image from a series of target images belonging to the same target for subsequent video Structured analysis. However, this strategy has two problems. First, how to evaluate the quality of the target image. Currently, there are relatively complete quality evaluation methods (such as ambiguity, angle, etc.) for face targets, but similar evaluation methods are not suitable for structured targets such as pedestrians, motor vehicles, and non-motor vehicles. For example, although a picture of a squattin...
