1. A computer-implemented method for processing the content of a digital image of a microscope sample, the method comprising, by at least one hardware processor: receiving an identification of one or more algorithms over at least one network; receiving an identification of one or more digital slide images over the at least one network; receiving one or more parameter data for the identified one or more algorithms, wherein the one or more parameter data comprises a definition of a sub-region of at least one of the one or more digital slide images; retrieving the one or more digital slide images; and executing the identified one or more algorithms to analyze the identified one or more digital slide images, wherein, for the at least one digital slide image, the execution of the identified one or more algorithms is constrained to the defined sub-region of the at least one digital slide image.
