Abstract
A method for removing satellite trails from images includes the following: obtaining an initial image having stars, locating stars in the image, removing the located stars from the initial image to form a star-removed image, locating the satellite trail in the star-removed image, determining brightness information for the satellite trail in the initial image, creating a satellite-trail-containing image with only satellite trail brightness information based on the determined brightness information, and subtracting the satellite-trail-containing image from the initial image to remove the satellite trail so as to form a satellite-trail-removed image. Systems for removing satellite trails from images are also provided, as are other aspects.
Claims20
A method of removing a satellite trail from an image comprising:
- obtaining an initial image having stars;
- locating stars in the image;
- removing the located stars from the initial image to form a star-removed image;
- locating the satellite trail in the star-removed image;
- determining brightness information for the satellite trail in the initial image;
- creating a satellite-trail-containing image with only satellite trail brightness information based on the determined brightness information;
- and
- subtracting the satellite-trail-containing image from the initial image to remove the satellite trail so as to form a satellite-trail-removed image.
A system for removing a satellite trail from an image comprising:
- a telescope having an imaging device;
- and
- a controller in communication with the telescope, the controller including a memory for storing instructions that when executed by the controller cause the controller to:
- receive an initial image having stars;
- locate stars in the image;
- remove the located stars from the initial image to form a star-removed image;
- locate the satellite trail in the star-removed image;
- determine brightness information for the satellite trail in the initial image;
- create a satellite-trail-containing image with only satellite trail brightness information based on the determined brightness information;
- and
- subtract the satellite-trail-containing image from the initial image to remove the satellite trail so as to form a satellite-trail-removed image.
