cpl_mask * | detsat (cpl_image *nscience, cpl_parameterlist *hpars) |
A SatelliteMap is constructed from ScienceFrames using the Hough Transform to detect long linear features, and using the inverse transform to mask these features in a pixelmap. | |
cpl_image * | hough_transform (cpl_image *img, float thre) |
Compute a Hough Transform on an image. |
This module provides functions to detect satellite trails via Hough transformation

A SatelliteMap is constructed from ScienceFrames using the Hough Transform to detect long linear features, and using the inverse transform to mask these features in a pixelmap.
Note that for images without satellite tracks the inverse transform produces a pxxelmap without bad pixels. It is probably easier just to save these (highly compressed) images than trying to distinguish in subsequent operations between SatelliteMaps with and without satellite tracks
