Problems solved by technology
However, there is a common problem in the application of face recognition technology in the security scene: due to the low pixel of the camera in the security scene, the face does various movements, the influence of light, and the distance between the person and the camera is too close or too far etc., resulting in blurred images sent to face recognition
Blurred face images are used for face recognition, on the one hand, it affects the effect of face recognition, on the other hand, it also leads to a lot of invalid face recognition, thus increasing the computational cost of face recognition devices

The invention discloses an image quality detection method and device and a storage medium, which are used for detecting image quality, reducing invalid face recognition and improving face recognitioneffect. The image quality detection method includes receiving an image to be detected; preprocessing the image to be detected; the image quality level corresponding to the image to be detected is determined by using a pre-trained image classification model, wherein the image classification model is trained by using a support vector machine SVM algorithm based on a sample image with an image quality level tag.
Description
technical field [0001] The present invention relates to the technical field of image processing, and in particular to an image quality detection method, device and storage medium. Background technique [0002] The use of face recognition technology is becoming more and more widespread, bringing convenience to people's lives. However, there is a common problem in the application of face recognition technology in the security scene: due to the low pixel of the camera in the security scene, the face does various movements, the influence of light, and the distance between the person and the camera is too close or too far And so on, the image sent to face recognition is blurred. Blurred face images are used for face recognition. On the one hand, it affects the effect of face recognition. On the other hand, it also leads to many invalid face recognitions, thereby increasing the calculation cost of the face recognition device. [0003] Therefore, how to detect the image quality t...
