CPICS – Continuous Particle Imaging Classification System

CPICSOur Continuous Particle Imaging and Classification System (CPICS) is an imaging sensor that produces unprecedented results for in-situ aquatic microscopy of seawater, freshwater and laboratory samples. Using darkfield illumination, the CPICS-1000-e captures high-resolution color images, showing features as small as 10µm and as large as several cm. Color information is key to high-accuracy classification while also providing important physiological information such as pigmentation due to grazing on phytoplankton. Because of its open-flow approach to water sampling, the delicate structures of plankton and particles remain intact as do predator-prey interactions.

CPICS deployment at 60ft depth.

The CPICS-1000-e is our latest development, which features embedded processing, region of interest (ROI) extraction, and on-board plankton classification. Stand-alone deployments on CTD Rosettes and autonomous platforms or vehicles – from large research vessels to row boats – make CPICS-1000-e an indispensable tool for researchers and resource managers alike.

ROImanage – Image Data Management Software

The ROImanage software product is a browser-based application used for manually categorizing images that are collected by the CPICS family of instruments. Users can create an unlimited number of named categories into which they can drag and drop images to create data sets for further analysis or for viewing based on search criteria. ROImanage is also the base application with which our automated classification software module ROIclass operates.

Sample data is shown below of a recent research expedition where CPICS was attached to a CTD profiling system.


Plankton Diversity

Biodiversity on the plankton for 22 species classified automatically using deep learning. A CPICS-1000-1x was installed on an OceanCube Observing system and deployed at Habu Research Station, Oshima Island, Toyko, Japan as part of the CREST project, Professor Hidekatsu Yamazaki, PI. Images were transferred to WHOI in real-time and classified using the DICE Deep Learning product provided by COV.
Note the decrease in biodiversity in the fall of 2014 but not in 2015, suggesting environmental conditions are changing.Slide41
