ECCV 2012 WORKSHOP QU3ST - 2.5D Sensing Technologies in Motion: The Quest for 3D Call for Papers A selection of the best papers presented to the workshop will be published in a Special Issue of IET Computer Vision. Website: http://qu3st.weebly.com Deadline: June 27, 2012 Structure-from-Motion (SfM) is a passive and now mature methodology that facilitates the 3D reconstruction of sparse features while estimating the cameras displacement over time. SfM has recently been given a unifying framework based on the concept of generic camera models. Recent advances in active sensor technologies (Time-of-Flight cameras, structured light such as the COMET, RGB-D cameras such as the Kinect, LIDARs such as the Velodyne and so on) permit to easily capture a 2.5D view of the scene in one-shot. These sensors are getting increasing popularity in robotics applications, cultural heritage or computer-aided surgery, amongst others. However, these sensors usually do not solve the temporal registration problem, required to produce a 3D model by stitching together the multiple 2.5D views. The scientific community has recently tackled the problem of solving 2.5D sensor motion tracking, but a unifying modeling has not been yet proposed. This workshop intends to gather the two communities working on active and passive 3D vision with the goal of integrating active and passive technologies in a unifying framework. More specifically, this workshop will address, but will not be limited to, the following questions and issues: Pose estimation of active sensors; Active sensors in dynamic environments; Rigid and non-rigid scenarios; Optical flow computation from 3D active sensing; 2D/3D fusion; Structure-from-motion vs motion-from-structure (registration); 3D models from multiple 2.5D views; Optimization of the 3D reconstruction from multiple shots; Data structures for large-scale/long-sequence reconstruction. Prospective authors are invited to submit a ten-page paper (ECCV format) via the workshop web-page (http://qu3st.weebly.com/submission.html). The papers will be reviewed by an international Program Committee (http://qu3st.weebly.com/people.html). Accepted papers will be presented in single-track oral sessions as well as a poster session (all papers are allocated the same number of pages). Accepted papers will be published on the DVD included in the main conference proceedings.
