MAZOOPS goes out to sea with the Cal-Echoes Cruise |
Graduate students Christian Briseno and Lina Lawrence took the second version of our zooplaknton imaging sonar (MAZOOPS) out on the R/V Melville as part of the Cal-Echoes Research Program. This version of MAZOOPS provides high-resolution (~30 micron) optical images and high-frequency, broadband... |
OmniCam:
 |
The OmniCam is a omnidirectional, high resolution, high speed, underwater imaging system designed to record the radiometric light field in the open ocean. These data are important in understanding the temoral and spatial fluctuations of the ambient light field in the open ocean. In addition, these... |

"Enhanced extended range underwater imaging via structured illumination" published in Optics Express |
Dr. Jaffe's work investigating the use of structured illumination for extended range underwater imaging systems (Enhanced extended range underwater imaging via structured illumination) appears in Vol. 18, Issue 12 of Optics Express this month. A pdf of the article is available here. |

Compressive Sensing |
I'm starting work today on a paper related to reconstructing a two-dimensional image of a fish from many observations of broadband scattering. Thus far, we have employed conventional dense reconstruction methods such as the inverse Radon transform and assumed a known geometry. This has lead to... |
ZOOPS:
 |
The ZOOplankton Sonar (ZOOPS) is a multiview, multimodal acoustic and optical zooplankton sonar system. It combines multiple, broadband acoustic sensors with a high-resolution camera and narrowband optical illumination. The system aims to provide enhanced information of zooplankton distributions in... |

WACV paper on multi* fusion submitted last week |
Last week we submitted a paper to the 2009 Worshop on Applications of Computer Vision (WACV). The paper presents some recent results on fusing multiple views and multiple modalities together to improve classification performance. The application was to zooplankton classification which has... |
FIDO-PHI-PI
 |
Fido-Phi-Pi is a modification of Fido-Phi, designed to develop an in situ 3-dimensional stereo particle image velocimetry system. The data collected with Fido-Phi-Pi is analyzed to better our knowledge of water velocities and turbulent flows in the ocean. Along with understanding the physical... |
LBath: Microbathymetric Laser Imaging
 |
A Microbathymetric Laser Imaging System:The submersible laser bathymetric (LBath) optical system is capable of simultaneously providing visual images and generating bathymetric maps of the sea floor with centimeter spatial and depth resolution. The system operates at roughly 10 m above the sea... |
LUMIS
 |
Our primary applications for LUMIS are in situ studies of (1) phytoplankton taxa and spatial variations; and (2) coral fluorescent pigment distributions. We have conducted plankton-related experiments in oligotrophic (Gulf of Eilat, Red Sea), eutrophic (Saanich Inlet, B.C., Canada), and coastal (... |
