Claim One:
1. A method for recognizing a human interaction depicted in a two-dimensional image, the method comprising, algorithmically: detecting a plurality of human face locations of people depicted in the image; determining a three-dimensional spatial arrangement of the people depicted in the image based on the detected human face locations; performing a proxemics-based analysis of the three-dimensional spatial arrangement of the people depicted in the image, wherein the proxemics-based analysis identifies cues in the three-dimensional spatial arrangement that are relevant to human interactions; and classifying the image as depicting a type of human interaction using visual proxemes, wherein the visual proxemes comprise a set of prototypical patterns that represent commonly occurring people interactions; wherein the image is created by a camera positioned at a camera viewpoint relative to a reference plane, and the method comprises estimating the camera viewpoint and using the estimated camera viewpoint to classify the image.
