Abstract

The embodiment of the invention provides an image screening method and device. The method comprises the following steps: obtaining an image frame sequence to be screened, wherein, each image frame inthe image frame sequence to be screened comprises a first target object; obtaining an image frame sequence to be screened. Determining target attribute data of a preset attribute of a first target object in each frame of an image to be screened by using a preset image feature evaluation model; According to the target attribute data of the first target object, determining the target confidence level corresponding to the image to be screened in each frame for the first target object in each image to be screened. According to the target confidence level corresponding to the image to be screened in each frame, the target image whose target confidence level reaches the preset recognition condition is screened out from the image frame sequence to be screened. The embodiment of the invention realizes automatic screening of images, shortens screening period and improves screening efficiency.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image screening method and device. Background technique [0002] In the video surveillance technology, during the process of collecting images, the image acquisition equipment will collect multiple frames of images containing target objects, wherein the above target objects include but not limited to human faces, pedestrians, license plates and vehicles. Factors such as the posture of the target object in the image, the degree of occlusion and / or the occluded part, the brightness of the area, and the degree of blur of the area determine to a certain extent whether the target object contained in the above-mentioned multi-frame images is easy to be recognized. [0003] When the above multi-frame images include images containing target objects that are not easily recognized, if all the above multi-frame images are recognized, the above multi-frame images include images o...
