Paper Abstract

As more and more applications for particle hologram have been developed, various methods for holographic image analysis have been studied. Being the preliminary task of holographic image processing, many analysis systems of 2D cross-sectional holographic field images have been developed. This presentation describes an on-line image processing system of particles auto-measurement for particle holograms. In this system, the 2D cross-sectional images of holograms are obtained using off-axis retrieval method. The whole processing task is divided into three sub-tasks. First, using an auto threshold selection approach, all the candidate particles are segmented. Then, the overlapped particles are separated and the basic parameters for the candidate particles are calculated. Finally, the candidate particles are verified using the parameters obtained above, and statistical data for the verified particles are worked out. At last, experiment results are given out to show the feasibility of this approach.
