The invention discloses a character attribute information identification method and device and an electronic device and belongs to the field of image processing. The method comprises the steps of obtaining an image containing a face, identifying the face, obtaining character identity information and initial character attribute information, searching for historical character attribute information corresponding to the character identity information, and determining the character attribute information which is identified this time according to the initial character attribute information and the historical character attribute information. According to the character attribute information identification method, through identification of the face on the image, the character identity information and the initial character attribute information are obtained; the character attribute information which is identified this time is determined according to the initial character attribute information and the historical character attribute information corresponding to the character identity information; the problem that according to a relevant technology, geometrical features extracted from the face image are influenced greatly by the brightness and the illumination angle in a face area is solved, and the accuracy of character attribute information identification is improved.
Description
technical field [0001] The present disclosure relates to the field of image processing, and in particular to a method, device and electronic equipment for identifying person attribute information. Background technique [0002] Human attribute information recognition has potential applications in many fields such as image processing, identity authentication, and robot vision. For example, in the field of image processing, it is possible to perform targeted processing on the characters in the image according to the identified attribute information of the characters. [0003] In related technologies, geometric features required for character attribute information recognition are usually extracted from face images, and various machine learning algorithms are used to train the extracted geometric features. For example, when the person attribute information includes age information and gender information, the NMF (Non-negative Matrix Factorization, non-negative matrix factorizati...
