[0050] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0051] The present invention provides a method for improving the resolution of a single-frame infrared image, the overall process of which is as follows figure 1 shown. The input single-frame low-resolution infrared image is divided into two paths. Send all the way to the image super-resolution branch, and perform super-resolution reconstruction through the image super-resolution network. Among them, the image super-resolution network draws on the basic structure of ESRGAN. The other way is sent to the gradient super-resolution branch. First, the infrared image is dehazed to enhance the detailed information of the image, and then the gradient image is extracted, and then the gradient image is reconstructed through the gradient super-resolution network. In the gradient super-resolution process, the gradient super-resolution network introduce...
