PARTICLE DOPPELGÄNGERS

A live particle mirror in which grains begin on the floor, rise into detected performers and remain bound to each body until that performer fully leaves the scene.

Particle Doppelgängers reconstructs performers as independent particle bodies. At rest, the particles live near the floor. When a person appears, body segmentation supplies a silhouette and the system samples targets throughout that shape. Persistent performer slots preserve color, particle population and identity between frames. Limbs are protected from temporary segmentation loss, and scattering begins only when the whole performer has actually left, preventing a hand or arm crossing the camera edge from destroying the body.
