Simulated space-based optical star image dataset with dim and small space targets

This data set is a space-based optical star image data set obtained based on computer simulation, which contains moving dim small space targets. The data is based on a star image sequence, and each sequence contains 8 frames of simulated star images, which can contain different numbers, velocities, motion directions, and signal-to-noise ratios of simulated small dim targets; Stars in the image background are generated based on the SAO catalog; The image background can contain stray light or slowly moving stars. This dataset can be used for the research of space dim small target detection methods.
