Proximity framing in a video system

A system comprising:

• a video processor (106) comprising:
• a head detection model (112) configured to generate head detection information for an image of a video stream, wherein the head detection information identifies a plurality of heads detected in the image,
• a frame generator (116) configured to generate a plurality of head frame definitions for an image of an input video stream, wherein generating the plurality of head frame definitions comprises:
• obtaining, using a head detection model and for an image of a video stream, head detection information, wherein the head detection information identifies a plurality of heads detected in the image;
• obtaining a plurality of buffer bounding boxes, wherein obtaining the plurality of buffer bounding boxes comprises:
• obtaining a plurality of head buffer bounding boxes for the plurality of heads detected in the image, and
• combining at least two of the plurality of head buffer bounding boxes into a proximity buffer bounding box;
• identifying a set of templates based on the plurality of buffer bounding boxes;
• creating, individually, the plurality of head frame definitions for the plurality of buffer bounding boxes using the set of templates;
• and
• an image framing processor (114) configured to process the video stream using the image frame definition.
