Automated processing pipeline has been developed for streak detection from CCD images.
- class="label">•
The prototype pipeline is tuned for ground- and space-based observing scenarios.
- class="label">•
About 90% of the long (>100 pixels) and bright (SNR > 1) streaks can be detected.

Average processing time is 13 s for a typical 2k-by-2k CCD image.
