Image processing for digital holograms of marine particles and organisms

Zonghua Liu, John Watson, Alastair Allen

Research output: Chapter in Book/Report/Conference proceedingPublished conference contribution


A set of image processing approaches are proposed for processing digital holographic images of plankton. The images are segmented to produce regions of interest (ROI) of plankton, and then the shape description of plankton is normalized which is invariant under the transformations of translation, scaling, skewing and rotation. Also break points of the normalized shape contour curve are detected and then the curve is presented compactly by a polygon based on those points.
