Claim:
1. A method of rapid distinction using an e-Petri device having a light detector, the method of rapid distinction comprising: (a) acquiring at predefined time intervals multiple time-lapse movie images of a specimen when the specimen is located on a specimen surface of a transparent layer disposed on a sensing surface of the light detector, wherein each time-lapse image is constructed from a plurality of snapshot images sequentially sampled by the light detector, wherein each snapshot image is a projection image based on illumination transmitted through the specimen, and wherein the plurality of snapshot images include projection images sequentially captured by the light detector while the specimen is sequentially illuminated at different angles of incidence using an illumination source; (b) tracking one or more features of one or more entities in the specimen using the time-lapse movie images; and (c) categorizing each of the one or more entities based on the tracked features, wherein categorizing each entity of the one or more entities comprises categorizing as either an entity of interest or as debris, wherein the entity is categorized as an entity of interest if it is determined that the features of the entity change shape between the time-lapse movie images, and wherein the entity is categorizing as debris if it is determined that the features of the entity do not change shape between consecutively acquired time-lapse movie images.
