Disclosed is a method of requesting and receiving a photograph based on three parameters: a supplied photograph, Exchangeable Image File (EXIF) data defining the characteristics of the requested photograph, and a description of content that is missing in the supplied photograph and needs to be present in the requested photograph.

Photo Request Using an Image and a Missing Content Description

Smart phones and other hand-held devices with cameras have made digital photography ubiquitous. Post-processing techniques exist that can analyze a photograph and identify the contents that comprise the photograph. Further character recognition algorithms are able to extract textual content from the photograph.

Presently, methods exist that recognize objects in a photograph and can automatically generate descriptive content [1, 2]. Common search engines offer image search capabilities that can find images based on a text or an image query [3]. Additionally, art exists that can reconstruct missing pixels in an image by extending neighboring pixels
(i.e., vectoring) [4].

The problem is that, when a photograph exists that partially captures a scene, there is no system or method to complete the scene in situations where vectoring is not feasible.

The proposed system enables a first user to request a new photograph based on the following information:

1. An existing photograph (optionally an annotation indicating one or more regions that are missing)

2. A location identifier and a time window within which the new photograph is requested

3. A set of EXIF data

4. A description of content that is missing in the supplied photograph

The system monitors the request for potential fulfilment. When a second user becomes available who matches the request characteristics (essentially #2 above), the system obtains a new photograph from the second user. Once the system verifies that the missing regions are present in the new photograph, and the regions' contents match the supplied description, it notifies the first user about the completion of the request. Note that the identity of the two users is preserved in this process.

To implement the system in a preferred embodiment:

1. Pre-configuration: a first user and a second user opt-in to accept requests for new photographs based on previously submitted photographs

2. A first user, using the steps in an existing method, receives Exchangeable Image File (EXIF) data and instructions from the cloud service to take a photograph from a smart camera

3. The first user is unable to obtain a photograph as instructed, and submits a request to the cloud service via the method running within the associated (first user's) camera consisting of the following data:

A. An existing photograph taken from associated (first user's) camera

  (optionally, the user annotates the one or more regions that are missing)
B. A description of the content that needs to be pres...
