Claim:
1. A method of classifying white blood cells (WBCs) in a biological sample on a substrate, the method comprising: acquiring, by an image acquisition device, a plurality of images of a first location on the substrate; determining, by a classifier using one or more processing devices, the classifier executing a first classification process, that a given object in the plurality of images is associated with a first classification group selected from a set of multiple WBC classification groups, wherein the first classification process uses a first set of features to select the first classification group for the given object; determining, by a classifier using one or more processing devices, the classifier executing a second classification process, that the given object is associated with a second classification group, wherein the second classification process uses a second set of features different from the first set of features; in response to determining that the given object is associated with the second classification group, changing a classification of the given object; displaying, on a user interface, a representation of the given object and the corresponding classification; and removing non-WBC objects from the images prior to classifying the objects, wherein the non-WBC objects include one or more of platelets, clumps, giant platelets, and micromegakaryocytes.
