Systems and methods for extending selectable object capability to a captured image using an alteration pattern

A computer-implemented method comprising:

• for a given content item, modifying the content item by:
• identifying one or more objects in the content item;
• applying an alteration pattern to a portion of the content item corresponding to an object of the one or more objects in the content item;
• applying a control watermark to at least one portion of the content item, wherein the control watermark embeds metadata indicative of the applied alteration pattern;
• and
• causing, based at least in part on a request, and based at least in part on the applied alteration pattern and the applied control watermark, supplemental information related to the object to be provided to a computing device.

A system comprising:

• control circuitry configured to:
• capture an image of a content item, wherein an alteration pattern is applied to a portion of the content item corresponding to an object in the content item;
• detect, in the captured image, a control watermark applied to at least one portion of the content item;
• extracting, from the control watermark, embedded metadata indicative of the applied alteration pattern;
• based at least in part on the embedded metadata indicative of the applied alteration pattern, identifying a boundary of a region of the captured image comprising the applied alteration pattern;
• and
• cause a portion of the captured image within the identified boundary to be selectable to access, based at least in part on the embedded metadata of the control watermark, supplemental information related to the object.
