As the demand for astronomical observations continues to grow, the aperture of telescopes is increasing, with segmented primary mirrors becoming a prevailing trend. However, segmented telescopes require a series of complex steps to ensure precise alignment between the individual segments, achieving diffraction-limited imaging performance.

1. Introduction Salient object detection (SOD) is an important preprocessing method in computer vision tasks, with applications in video detection and segmentation [1], semantic segmentation [2], object tracking [3], etc. CNN-based models for RGB SOD have yielded great performance in localizing salient objects [4,5,6,7,8]. However, it is still difficult to localize the salient object accurately in scenes such as those with low contrast or objects with a cluttered background.
