%X Two image processing methods are presented and compared for particle detection based on digital holography. The image processing methods are developed based on edge detection and threshold based segmentation. The proposed methods have been applied on reconstructed images of holograms of ceramic beads and certified microspheres. Particle size distribution obtained for both methods are found to be in good agreement with the actual size; but the processing speed for threshold based detection is found to be faster in comparison to the edge detection method. © 2014 Trans Tech Publications, Switzerland.
