Embodiment Construction

[0019] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] A method for converting an infrared human face image to a visible light human face image, comprising the following steps:

[0021] Step 1. On the one hand, use the images in the existing infrared face database and visible light face database; on the other hand, use surveillance cameras to collect infrared images of people's faces and visible light face images; construct infrared and visible light face data sets;

[0022] Step 2. Align the images in the face database according to the relative positions of the eyes, and transform them to the same size.

[0023] Step 3, the entire data set is randomly selected and a training data set, a verification data set, and a test data set are in accordance with the relationship of 7:2:1.

[0024] In this embodiment, the size of the face image is 48*64 pixels.

[0025] Step 4. Construct the confront...

Abstract

The invention relates to a method for converting an infrared face image into a visible light face image. The method comprises the following steps: constructing an infrared and visible light face dataset; aligning the images in the face data set according to the relative positions of the eyes, and converting the images into the same size; constructing a training data set, a verification data set and a test data set; constructing an adversarial generative network, and performing network training by adopting a cyclic adversarial generative mode; and generating a transformation network from the infrared face image to the visible light face image. The method is reasonable in design, reduces dependence on supervision data, well solves the problem of conversion from the infrared face image to the visible light face image, can improve the accuracy of infrared face recognition by means of a visible light face recognition method, and can be widely applied to night infrared camera shooting occasions.

Description

technical field [0001] The invention belongs to the technical field of infrared image processing, in particular to a conversion method from an infrared face image to a visible light face image. Background technique [0002] In the existing video surveillance network, it is often required to realize the 24-hour all-weather monitoring function. When the lighting is not good at night, infrared camera becomes a must. Improving the recognition rate of infrared face images has important practical significance for improving the effect of night monitoring. [0003] In order to improve the recognition rate of infrared face images, on the one hand, it is possible to start from infrared face images and conduct in-depth research on recognition methods based on infrared face images; At the middle level, there is still a huge gap compared with the recognition rate of visible light face images. On the other hand, the research on visible light face recognition technology has made the grea...
