“…The choice of percentage of coe cients has the most impact on lossy compression quality. A highly e↵ective method for object detection by Zheng et al [14] is used to evaluate the quality of lossy compression and object detection at various levels. In the original data, a total of 401 objects can be extracted with this method on a 64MB FITS container.…”

“…Thresholding segmentation [1] is an important process for space object recognition and extraction in star images. Stars and skylight backgrounds are separated by differences in grayscale, and segmentation thresholdings commonly used today are global thresholdings [2][3][4][5][6][7][8][9][10][11][12][13] and local thresholdings [14][15][16][17][18][19]. A global thresholding is to specify a unified thresholding for all pixels of an image, such as the Otsu method [2][3][4][5], maximum entropy method [6][7][8][9][10] and the minimum error thresholding method [11], which are only applicable to star images where the gray levels of objects and backgrounds are clearly distinguished.…”
