1. A digital content subscribing device comprising: a display; a non-transitory computer readable memory storing software instructions; and a processor coupled with the display and the non-transitory computer readable memory, and that, upon execution of the software instructions, operates as: a recognition module configurable to: acquire a digital image that includes images of a plurality of objects; and derive a set of descriptors associated with the plurality of objects from the digital image as a function of an implementation of at least one object recognition algorithm; an object analysis module coupled with the recognition module and configurable to: identify subsets of descriptors relevant to object features of objects in the plurality of objects; recognize some of the plurality of objects as recognized objects as a function of the subsets of descriptors; and weight the subsets of descriptors according to relevancy rules as a function of the recognized objects thereby forming weighted subsets of descriptors; and a subscription agent coupled with the object analysis module and configurable to: receive a list of content channel identifiers for the recognized objects based on a submission of the weighted subsets of descriptors as a query to a channel database; subscribe to at least one digital content channel associated with the recognized objects based on content channel identifiers; render, via the display, digital content from the at least one digital content channel and retrieved from a source device.
