- Abstract: Astronomical images provide information about the great variety of cosmic
objects in the Universe. Due to the large volumes of data, the presence of
innumerable bright point sources as well as noise within the frame and the
spatial gap between objects and satellite cameras, it is a challenging task to
classify and detect the celestial objects. We propose an Adaptive Thresholding
Method (ATM) based segmentation and Back Propagation Neural Network (BPNN)
based cosmic object detection including a well-structured series of
pre-processing steps designed to enhance segmentation and detection.

Segmentation [100.0316479167605]
A class activation map (CAM) can only locate the most discriminative part of objects.
We propose spatial structure constraints (SSC) for weakly supervised semantic segmentation to alleviate the unwanted object over-activation of attention expansion.
Our approach achieves 72.7% and 47.0% mIoU on the PASCAL VOC 2012 and COCO datasets, respectively.

We propose a novel cross-scope spatial-spectral Transformer (CST) to investigate long-range spatial and spectral similarities for single hyperspectral image super-resolution.
Specifically, we devise cross-attention mechanisms in spatial and spectral dimensions to comprehensively model the long-range spatial-spectral characteristics.
Experiments over three hyperspectral datasets demonstrate that the proposed CST is superior to other state-of-the-art methods both quantitatively and visually.
