Stephan Morgenthaler, Mikaël Martino, Jean-Marie Petit, Shuangqing Liao
Context. The ESA Gaia mission provides a unique time-domain survey for more than 1.6 billion sources with G less than or similar to 21 mag. Aims. We showcase stellar variability in the Galactic colour-absolute magnitude diagram (CaMD). We focus on pulsatin ...
EDP SCIENCES S A2019Automatic and Accurate Shadow Detection using Near-Infrared Information
Sabine Süsstrunk, Dominic Rüfenacht
We present a method to automatically detect shadows in a fast and accurate manner by employing the inherent sensitivity of digital camera sensors to the near-infrared (NIR) part of the spectrum. Shadows are generally found in the dark parts of an image, be ...
