1. A computer-implemented method for processing two-dimensional (2D) image data, the method comprising: identifying, at least a first person and a second person depicted in the 2D image data based on a spatial proximity and a scale of the first and second person in the plurality of 2D images, wherein the 2D image data depicts the first and second person interacting with one another in a correlated activity; generating, by operation of one or more computer processors, a 2D pose estimation for at least the first person, wherein the 2D pose estimation is generated, at least in part, to account for constraints on positions of body parts of the first and second person resulting from the first person and second person interacting with one another in the correlated activity.
