In-situ Particle Imaging and Classification
Our Continuous Particle Imaging and Classification System (CPICS) 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 1µm 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 completely intact as do predator-prey interactions.
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.
In-situ Power + Analysis + Storage
The CPICS SmartModule is a combination power pack and processing add-on module that enhances the capabilities of the CPICS in-situ aquatic microscope. With its built-in processing system, full-frame images captured by the CPICS camera are reduced to much smaller regions of interest (ROIs) that are stored locally within the unit. An internal battery allows the CPICS system to function as a complete standalone intelligent image logger and processor that can be added to a variety of vehicles and instrument packages without the need to modify their existing communication or power configuration.
Coastal Observatory System
An OceanCube is an un-manned underwater coastal observatory system designed to provide real-time data and images. A central node supports a variety of biological, physical, and chemical sensors and is optionally connected to as many as four satellite nodes at the corners of a cubic volume that provide current and temperature information. To observe the behavior of fish, stereo camera modules with hydrophones can also be connected. A cable from a shore laboratory to the central node is used to supply power, remotely control individual instruments and to transfer data back to shore at high speed.
Software for Image Organization
The ROIsort 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. ROIsort is also the base application with which our automated classification software module ROIclass operates.
Software for Image Analysis
The ROIclass software application is an add-on module that extends the manual capabilities of the ROIsort browser-based application by generating automatic classifications of images that were collected by the CPICS family of instruments. Using the manually classified Region Of Interest (ROI) sets created in ROIsort application are used by ROIclass to build classifiers based on either Support Vector Machines or Random Forests. The user can also select from several types of machine vision descriptors that can represent the image in various ways for the training and running of the classifiers.
