Multi-frame infrared image super-resolution method and system based on feature cycle fusion

The embodiment of the invention provides a multi-frame infrared image super-resolution method and system based on feature cycle fusion. Comprising the following steps: circularly fusing features in sequence according to the sequence of input frames by using a cyclic fusion feature mechanism, and sending the fusion result to the next cycle for information transmission, so that too much time increase is not caused when multiple frames are processed, and meanwhile, a high-resolution result can be output; introducing and modifying a pyramid cascade deformable convolution alignment method. The main reason of the improvement of the deformable convolution alignment effect is the improvement of the number of offset groups; different offset group numbers can complement each other, the error-tolerant rate is improved, and the network is allowed to aggregate information from different positions. 本发明实施例提供一种基于特征循环融合的多帧红外图像超分辨率方法和系统，使用了循环融合特征的机制，按照输入帧的顺序依次循环融合特征，并将融合结果传至下一次循环进行信息的传递。于是处理多帧时不会带来太多时间上的增加，同时能输出高分辨率结果；引入金字塔级联可
