Abstract

The invention discloses a quality evaluation method and device of an image sample set and a storage medium. The method comprises the following steps: determining face sampling quality associated with a face target in a face sample image, and determining a first evaluation parameter of an image sample set according to the face sampling quality; determining a second evaluation parameter of the image sample set according to the distribution of the face sample images among different personnel categories; according to the number of effective sample images in the image sample set, a third evaluation parameter of the image sample set is determined, and the effective sample images are face sample images suitable for determining categories through a deep learning-based model; and evaluating the quality of the image sample set according to the first evaluation parameter, the second evaluation parameter and the third evaluation parameter.

Description

technical field [0001] The present application relates to the technical field of face recognition, and in particular, to a quality assessment method, device and storage medium for an image sample set. Background technique [0002] Face recognition technology needs to train a face recognition model based on deep learning through a large number of face sample images in the image sample set. For a face recognition model, the quality of the face sample images plays a decisive role in the accuracy of the trained face recognition model. Therefore, it is necessary to provide a quality assessment method that can assess the quality of the image sample set, so that people can evaluate the quality of the image sample set used for training the face recognition model, so as to exclude the problem before training the face recognition model. A sample set of images of poor quality. [0003] In addition, the face recognition model can be applied to different application scenarios. And the...
