Secondary craters on Europa and implications for cratered surfaces

Nature, 2005
For several decades, most planetary researchers have regarded the impact crater populations on solid-surfaced planets and smaller bodies as predominantly reflecting the direct ('primary') impacts of asteroids and comets. Estimates of the relative and absolute ages of geological units on these objects have been based on this assumption.

On Crater Verification Using Mislocalized Crater Regions

2017 IEEE Winter Conference on Applications of Computer Vision (WACV), 2017
Automatic crater detection in planetary images is an important task with many applications in planetary science, spacecraft navigation, landing, and control. Typically, crater detection algorithms consist of two main steps: candidate crater region extraction and crater verification.
