Embodiment Construction

[0071] The present invention will be further described below in conjunction with the accompanying drawings.

[0072] This embodiment is based on the pedestrian gender recognition model of extreme learning machine and color feature fusion. The model includes a feature extraction module and a perceptron function module. This embodiment specifically includes a training process and a recognition process. See figure 1 As shown, the present invention is a pedestrian gender recognition method based on the fusion of extreme learning machine and color feature, and the steps are as follows:

[0073] 1) Input training images with unmarked gender attributes, and then send them to the layered ELM for training to obtain the model M (M is the output weight β obtained by solving the objective function of the ELM autoencoder in the layered network ), and use the trained model M to extract the feature a of the training image;

[0074] 2) Extract the HSV color feature b of the input training im...

Abstract

The invention discloses an extreme learning machine and color feature fusion based pedestrian gender identifying method. The method includes extracting extreme learning machine features of training images whose gender attributes are not marked; extracting HSV color features of input training image whose gender attributes are not marked, combining the extreme learning machine features with the color features and thus obtaining fusion features, and training a pedestrian gender classifier by utilizing a linear SVM (Support Vector Machine) according to the fusion features and training image labels; extracting image features of a to-be-tested image by utilizing a model obtained through training and extracting HSV color features of the to-be-tested image, fusing the two kinds of features and thus obtaining the fusion features of the to-be-tested image, and classifying the fusion features by utilizing the pedestrian gender classifier of the linear SVM obtained in the training process. According to the invention, extreme learning features and color features of the input images are extracted and fused effectively, mutual complementation of the two kinds of features is realized, and pedestrian gender attributes are captured more effectively, so that pedestrian gender identification rate is improved.

Description

technical field [0001] The invention relates to computer vision and pattern recognition, in particular to a pedestrian gender recognition method based on extreme learning machine and color feature fusion. Background technique [0002] With the active promotion of "smart cities", thousands of video surveillance cameras gradually cover various public places, providing basic guarantee facilities for urban public safety management. Considering various factors such as anti-terrorism and national public security, the video surveillance system urgently needs a fast identification technology in the long-distance and non-cooperative state of the target, so as to quickly confirm the identity of pedestrians at a long distance and realize intelligent early warning. As an important auxiliary means of long-distance identification technology, pedestrian gender recognition technology is an indispensable part of the intelligent video surveillance system.
