Problems solved by technology

[0004] In practical applications, the annotation of labeled image samples usually consumes a lot of human and time costs
Moreover, for the same image sample, different people often give different labels, which leads to low accuracy of the label of the image sample; and the performance of the quality detection model is closely related to the accuracy of the label, so the low accuracy of the label Also reduces the performance of the quality detection model

Description

technical field [0001] The present application relates to the technical field of computer vision, and in particular, to a training method, an image quality detection method, an apparatus and a medium. Background technique [0002] In the field of computer vision technology, target recognition models can be used to recognize targets such as people, animals, vehicles, and characters contained in images. In practical applications, the target is far away from the camera, the lighting conditions are poor, and the imaging effect of the image acquisition device is poor, which may easily lead to poor image clarity and low resolution, thus affecting the target recognition effect. In order to improve the target recognition results, the image quality can be checked before target recognition, and the images with poor quality can be blocked from entering the target recognition model. [0003] The current image quality detection methods usually firstly label the image samples manually to...
