Cooperative Target Tracking by Multiagent Camera Sensor Networks via Gaussian Process
In this paper, we present learning-based robust cooperative control for camera sensor networks. The dynamics of each camera agent with the pan and tilt mechanism is modeled by the Euler-Lagrange equation.

Rapid tilt-series method for cryo-electron tomography: Characterizing stage behavior during FISE acquisition [PDF]
We and others recently developed rapid tilt-series acquisition methods for cryo-electron tomography on a Titan Krios G3i equipped with a single axis holder and a K-series direct electron detector and showed that one of these, the fast-incremental single ...

CameraTransform: A Python package for perspective corrections and image mapping
Camera images and video recordings are simple and non-invasive tools to investigate animals in their natural habitat. Quantitative evaluations, however, often require an exact reconstruction of object positions, sizes, and distances in the image.

Laparoscopic Camera Based on an Orthogonal Magnet Arrangement [PDF]
In this letter, we present for the first time a magnetic anchoring-actuation link with an auto-flip feature. This orthogonal magnetic arrangement relies on the placement of two permanent magnets such that their magnetic moments are respectfully ...
