Three-dimensional tracking of occluded objects using integral imaging

Abstract

We present experiments to illustrate tracking of occluded objects using three-dimensional (3D) integral imaging (II). Tracking of heavily occluded objects by conventional two-dimensional (2D) image processing may be difficult owing to the superposition of occlusion noise and object details. The effects of occlusion are remedied by 3D computational II reconstruction. We use a summation of absolute difference (SAD) algorithm between pixels of consecutive frames of a moving object for 3D tracking. SAD algorithm is not robust for 2D images of occluded objects; 3D computation reconstruction of the scene allows implementation of a SAD algorithm by reducing occlusion effects. Experimental results demonstrate 3D tracking of occluded objects. To the best of our knowledge, this is the first report on 3D tracking of objects using II.
