Ground-Based Cloud Image Segmentation Method Based on Improved U-Net

Applied Sciences
Cloud image segmentation is a technique that divides images captured by meteorological satellites or ground-based observations into different regions or categories.

Exploring the capabilities of astrophotonics for the precise alignment of segmented telescopes

Techniques and Instrumentation for Detection of Exoplanets XII
The next generation of large telescopes for direct imaging of exoplanets will require segmented primary mirrors. Over both long and short timescales, these telescopes experience segment misalignments which degrade the final science image. Adaptive optics (AO) systems can be used to correct these aberrations in real time.
