Abstract

A face gender recognition method based on Fireworks Deep Belief Network, which consists of original image preprocessing, training Deep Belief Network, optimizing the initial parameter space of Deep Belief Network with Fireworks Algorithm, and using the Deep Belief Network optimized by Fireworks Algorithm for face gender recognition . The present invention adopts the deep belief network to learn more abundant features of face image semantic information in the unsupervised stage, uses the firework algorithm to adjust the initial parameter space of the deep belief network in the supervised stage, and obtains a network model more suitable for recognition tasks.

Description

technical field [0001] The invention belongs to the technical field of face image gender recognition, and in particular relates to a method for determining the face gender recognition by using a firework algorithm to optimize the initial parameter space of a deep belief network. Background technique [0002] Face gender recognition technology has a wide range of applications in human-computer interaction, machine vision, identity verification, security systems, etc., and has become a research hotspot in recent years. Gender recognition systems for face images usually consist of three parts: face detection, feature extraction, and recognition. Extract the underlying visual features of the face image, and use these features as the input of the classifier to identify the gender of the face. The extraction of facial features is the key to gender recognition, and the quality of feature selection will directly affect the subsequent recognition accuracy. The commonly used artific...
