Use of Mathematic Morphological Operators for Processing the Smeared Images of A Camera without Shutter
چکیده انگلیسی

In the observation of space objects with a full-frame transfer CCD camera, the camera shutter is often removed, and therefore the smeared images are produced, which affect seriously the object detection and location. Based on the difference of geometrical morphology between star images and smears, a mathematical morphology method is proposed to process the smeared images. By comparing the position accuracies of stars and space objects before and after processing, it is verified that the morphological method can effectively remove the smears from astronomical images, and can significantly improve the detection rates and position accuracies of stars and moving objects. The result indicates that this is an effective method to eliminate the smearing effect.
