Embodiment Construction

[0031] The pedestrian attribute recognition method based on deep learning provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Such as figure 1 , figure 2 As shown, the pedestrian attribute recognition method based on deep learning provided by the present invention includes the following steps carried out in order:

[0033] (1) Using the classic Deeplab-v2 network in the image semantic segmentation method, the pedestrian image in the pedestrian attribute dataset is used as the input of the Deeplab-v2 network, and the output is the mask image of the pedestrian image;

[0034] The pedestrian image can be expressed as a multi-dimensional matrix mathematically, and the mask image is a matrix with the same dimension as the pedestrian image; the pedestrian body area element in the pedestrian image is set to 1, and the matrix obtained by setting the background area element to 0 is is the ...

Abstract

The invention discloses a pedestrian attribute identification method based on deep learning. The method comprises the following steps: taking a pedestrian image as the input of a Deeplab-v2 network to obtain a mask map; multiplying the mask image and the pedestrian image element by element to obtain a foreground image, negating the mask image, and multiplying the mask image and the pedestrian image element by element to obtain a background image; constructing a pedestrian attribute identification network, and combining the regional-level ternary loss function and the weighted cross entropy loss function as a loss function of the network; taking the pedestrian image, the foreground image and the background image as input of a pedestrian attribute recognition network, calculating a networkloss value by utilizing a loss function, optimizing the network through a random gradient descent method, and storing network parameters; and initializing a pedestrian attribute recognition network byutilizing the pedestrian attribute recognition network parameters, and inputting pedestrian images to obtain an attribute recognition result. The method is reasonable in design, so that the accuracyof pedestrian attribute recognition can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of image processing, in particular to a pedestrian attribute recognition method based on deep learning. Background technique [0002] In recent years, people have paid more and more attention to public security issues. A large number of surveillance cameras are used in shopping malls, subway stations, intersections and other places where there are dense crowds and public security incidents are prone to occur. Surveillance videos can provide people with a lot of useful information. Pedestrian attribute recognition can identify some observable external feature information of pedestrians in the monitoring scene, such as gender, age, clothing, and belongings, etc. This information can provide clues for the public security department to detect criminal cases such as shopping mall theft and crowd fighting. Play an important role in maintaining national security. [0003] At present, pedestrian attribute recogniti...
