Deskribapena: Top: Raw video, as captured with an optical microscope. Botttom: processed video, after applying some filters and computer vision algorythms to detect and track bacteria. Video by Danny Villanueva, PhD student of the Group of Magnetism and Magnetic Materials (GMMMT) of the UPV/EHU.

Deskribapena: Top video: Motion of MTBs swimming in a microfluidic channel, recorded with an optical microscope and tracked using artificial vision algorythms. Bottom video: Horizonal component of the magnetic field (Hx) created by the bacteria in a planar magnetic sensor placed below the channel.

Deskribapena: Example of how an optically acquired video of Magnetotactic Bacteria (MTB) can be automatically analized by applying image sequencing techniques. Each moving bacterium is assigned an ID number, while their positions, orientations and velocities are calculated for each frame. Video created by Danny Yosmar Villanueva, from the Group of Magnetism and Magnetic Materials (UPV/EHU).
