Abstract
We introduce an algorithm for object discovery from RGB-D (color plus depth) data, building on recent progress in using RGB-D cameras for 3-D reconstruction. A set of 3-D maps are built from multiple visits to the same scene. We introduce a multi-scene MRF model to detect objects that moved between visits, combining shape, visibility, and color cues. We measure similarities between candidate objects using both 2-D and 3-D matching, and apply spectral clustering to infer object clusters from noisy links. Our approach can robustly detect objects and their motion between scenes even when objects are textureless or have the same shape as other objects.
