Claim 18:
19. A method of characterizing parameters for holographic microscopy of objects comprising the steps of:
receiving, by a processor, image data from a storage medium;
transforming, by a processor, the image data using a Hough circular transform to determine by a voting algorithm a first estimate of the number of objects in the image data and the objects approximate x, y position in a plane;
applying, by a processor, Lorenz-Mie analysis of the image data for each of the objects to determine an estimate of the radius and refractive index of each of the objects;
applying, by a processor, Maxwell Garnett effective-medium theory analysis of the image data for each of the objects to determine the effective diameter of a coating associated with the object;
identifying, by a processor, from one or both of estimated radii and estimated refractive indices those particles having a coating; and
generating a signal to the user indicating completed process.
