Stereo vision and segmentation
I will describe models and algorithms for the real-time segmentation of foreground from background layers in stereo video sequences. Automatic separation of layers from color/contrast or from stereo alone is known to be error-prone. Here, color, contrast and stereo matching information are fused to infer layers accurately and efficiently. The stereo-match likelihood is then fused with a contras...
متن کاملStereo Vision and Scene Segmentation
Scene segmentation is the well-known task of identifying the image regions corresponding to the different scene elements or segments Sk , k = 1, 2..., N belonging to a predefined set S par‐ titioning the scene in N subsets, each one corresponding to a scene object or to a region of interest. Beside being an important problem by itself, segmentation is also employed as a preliminary step in many...
متن کاملBimodal Active Stereo Vision
We present a biologically inspired active vision system that incorporates two modes of perception. A peripheral mode provides a broad and coarse perception of where mass is in the scene in the vicinity of the current fixation point, and how that mass is moving. It involves fusion of actively acquired depth data into a 3D occupancy grid. A foveal mode then ensures coordinated stereo fixation upo...
متن کاملFastSLAM with Stereo Vision
We consider the problem of performing simultaneous localization and mapping (SLAM) with a stereo vision sensor, where image features are matched and triangulated for use as landmarks. We explain how we obtain landmark measurements from image features, and describe them with a Gaussian noise model for use with a Rao-Blackwellized particle filter-based SLAM algorithm called FastSLAM. This algorit...
متن کاملStereo vision for Robotics
The human eye-brain system is responsible for the highest percentage of sensory data from the environment. A major part of this system which is unique to all predator species (including man) is the ability to perceive distance of various objects using their two eyes. This is one of the primary reasons that man and other predators have both their eyes on the same side of their head (i.e. front) ...
