Embodiment Construction

[0030] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the embodiments of the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the embodiments of the invention as recited in the appended claims.

[0031] Face attribute analysis methods can be divided into single-attribute analysis methods and multi-attribute analysis methods. The two analysis methods are briefly introduced below.

[0032] First of all, face single-attribute analysis methods can be roughly divided into the following two categories:

[0033] 1) Training an attribute classifier with ...

Abstract

Embodiments of the invention relate to a facial image series-based attribute identification method and device. The method comprises the following steps of: extracting facial attribute features in a facial image series through a convolutional neural network and a recurrent neural network; selecting a target facial attribute feature in the facial attribute features through a machine learning model; and when a plurality of primary attribute identification results obtained through identifying the target facial attribute feature by a plurality of preset classifiers are obtained, fusing the plurality of primary identification results to generate an advanced identification result of the facial image attribute identification. According to the method and device, the features between different facial images in the facial image series are correlated, and the complementary relationship between different images in the facial image series is fully mined, so that the problem of low correctness caused by single-facial image attribute identification in the prior art can be well avoided.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image recognition, and in particular to a method and device for attribute recognition based on a face image sequence. Background technique [0002] Biological features have been widely used in all aspects of daily life due to their uniqueness, safety and convenience. Due to the advantages of convenience, user-friendliness and non-contact, face biometric recognition technology has achieved rapid development in recent years. These developments are reflected in various research areas, including face detection, face feature extraction, classifier design, and hardware device manufacturing. [0003] In addition to the application of face biometric recognition technology in identity authentication, soft biometric analysis technology based on face images has also been favored by people and has been successfully applied in many cases. Facial soft biometric recognition, also known as facial ...
