Abstract

An embodiment of the present invention provides an image screening method and device, the method comprising: obtaining a sequence of image frames to be screened, wherein each frame of an image to be screened in the sequence of image frames includes a first target object; using a preset image The feature evaluation model determines the target attribute data of the preset attributes of the first target object in each frame of the image to be screened; for the first target object in each frame of the image to be screened, according to the target attribute data of the first target object, Determine the target confidence level corresponding to each frame of the image to be screened; according to the target confidence level corresponding to each frame of the image to be screened, select the target image whose target confidence level meets the preset recognition condition from the sequence of image frames to be screened. The application of the embodiment of the present invention realizes automatic screening of images, shortens the screening cycle, 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...
