Remote Sensing Image Super-Resolution Reconstruction Method for Ship Target Recognition
摘要
Abstract
The degradation of space-based remote sensing image resolution poses great challenges for the recognition of ship targets.Image super-resolution reconstruction technology can provide rich information for recognition tasks.However,if image super-resolution reconstruction and ship target recognition tasks are performed independently,the internal coher-ence between the two tasks will be ignored.Aiming at these problems,in order to explore the effective combination of image super-resolution reconstruction and target recognition tasks,a remote sensing image super-resolution reconstruction method for ship target recognition is proposed.Specifically,a full channel concatenation network is firstly designed,which replaces the residual connection with an adaptively weighted full channel concatenation,improves the fluidity and expression performance of each layer feature,and realizes efficient super-resolution reconstruction of remote sensing images.In order to further explore the potential of super-resolution reconstruction to improve the performance of ship target recognition,a joint network of super-resolution reconstruction and target recognition is proposed by introducing multi-task learning technology.The stable training of the joint end-to-end network is realized by multi-stage training optimization strategy,so as to guide effective mutual supervised learning between tasks.The experimental results on the public data set FGSCR-42 show that when the resolution of remote sensing images is degraded by 8 times and 16 times,the proposed super-resolution reconstruction network helps the accuracy of ship target recognition to increase by 33.27 and 17.48 percentage points respectively;the proposed joint network further improves the recognition accuracy by 1.75 and 1.91 percentage points.关键词
