The CPICS instrument has produced unprecedented results in the in situ aquatic microscopy of seawater, freshwater and laboratory samples. Using darkfield illumination, the CPICS captures high-resolution color images, showing features as small as 1µm. Research has shown that 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 generates fullframe images at 6-10 Hz/s. Target ROIs (regions of interest) are extracted and stored for further analysis and archival purposes.
Features are extracted from the recorded ROIs and go through an automated classification process to generate taxanomic IDs for each ROI. The automated process is trained by manual identification of ROIs to form a training set.
