1. A method for processing images generated by unsupervised end-users, the method comprising:
determining whether at least one digital image of a document was generated by scanning an original document or was not generated by scanning the original document, including using a processor for applying a resolution analysis test to a textured region of interest; and
sending at least one output indication of the determining operation,
wherein said image is captured by a client camera device, and wherein the resolution analysis test is performed, by a server deployed remotely vis-à-vis the client camera device, on an image I of the region of interest which is sent to the server and which, to conserve bandwidth, includes less than all of the original document
wherein the determining is performed for plural images of plural documents belonging to different known classes of documents for which the region of interest appears at respective different locations, known to the server, within the document, and
wherein the client camera device first sends the image at a first resolution to the server
which determines which class c from among said classes the image belongs to,
then the server commands the client camera device to send a region appearing at a location within the image,
which is known to the server to include the known location of the region of interest for class c,
and then the client camera device sends only the region and not the entire image, at a second resolution higher than said first resolution, to the server which applies said test.
