CRRF is used to estimate a depth image of hand given stereo RGB inputs. CRRF uses a novel superpixel-based regression framework that takes advantage of the smoothness of the hand’s depth surface. A RRF unary term adaptively selects different stereo-matching measures as it implicitly determines matching pixels in a coarse-to-fine manner. CRRF also includes a pair-wise term that encourages smoothness between similar adjacent superpixels. Experimental results show that CRRF can produce high quality depth maps, even using an inexpensive RGB stereo camera and produces state-of-the-art results for hand depth estimation. dates_date: 2017-08-24 dates_date: 2018-01-23 dates_date_type: accepted dates_date_type: published_online publication: 2017 IEEE International Conference on Computer Vision Workshops (ICCVW) publisher: IEEE pagerange: 614-622 event_title: International Conference on Computer Vision Workshop on Observing and Understanding Hands in Action event_location: Venice, Italy event_dates: 23 Oct 2017 event_type: workshop id_number: 10.1109/ICCVW.2017.78 refereed: TRUE issn: 2473-9944 citation_doi: 10.1109/ICCVW.2017.78 citation: Basaru, R.
