Active Segmentation
The Problem: For a robot to manipulate its environment effectively, it needs to know which parts of the world move together, and which are more or less independent. Humans can judge physical coherence quite reliably from purely visual information, but that seems challenging for our machines. This work develops active strategies for segmenting objects from the background by trying to set them in...
متن کاملActive Segmentation
The human visual system observes and understands a scene/image by making a series of fixations. Every fixation point lies inside a particular region of arbitrary shape and size in the scene which can either be an object or just a part of it. We define as a basic segmentation problem the task of segmenting that region containing the fixation point. Segmenting the region containing the fixation i...
متن کاملHyperspectral segmentation with active learning
This paper introduces a new supervised Bayesian approach to hyperspectral image segmentation, with two main steps: (a) learning, for each class label, the posterior probability distributions, based on a multinomial logistic regression model; (b) segmenting the hyperspectral image, based on the posterior probability distribution learnt in step (a) and on a multi-level logistic prior encoding the...
متن کاملActive Object Segmentation for Mobile Robots
The goal of active vision is to change intrinsic or extrinsic properties of the sensor in order to get new and improved information. In the case of 3-D object modeling from vision, this can mean moving the camera to view the scene from a new angle or to get a close-up view of an object that has been localized and is being modeled. We discuss using active vision to improve the speed and utility ...
