Abstract

The invention relates to a face and fingerprint-based gender recognition method using a machine vision and pattern recognition technology, and the method comprises the following specific steps: (1) representing image characteristics based on a bag-of-words model, in which a new method for supervising vision word creation is provided to eliminate redundant characteristic number of dimensions and enhance the dimensions helpful for gender classification; (2) putting forward an improved latent Dirichlet allocation (LDA) model to maximize classification intervals, thereby enhancing the recognitioncapability of the entire model; and (3) integrating face and fingerprint visual decisions, training the model separately, and obtaining the final decision through minimizing decision-making risk. Themethod provided by the invention has good robustness and discrimination capacity, and is verified in a large-sized database comprising faces and fingerprints of same persons. Results show that the method can well complete gender recognition, and can be used in all aspects of gender recognition.

Description

technical field [0001] The invention relates to a gender identification method, in particular to a collaborative gender identification method that fuses human face and fingerprint visual information. Background technique [0002] In recent years, gender recognition has gradually attracted the attention of more and more researchers in the fields of computer vision and pattern recognition. Physiologists and suspect identification experts mainly use human physiological characteristics for gender identification, and the visual information of human faces is their most commonly used physiological characteristics. At present, many existing methods mainly use face information for gender recognition. Usually, these methods are based on global features of faces (such as original pixels) and discriminative classification algorithms (such as SVM, Boosting). The visual information of fingerprints is also widely used in gender identification. Compared with human faces, due to the specia...
