Inverse Composition Discriminative Optimization for Point Cloud Registration

CVPR 2018poster

Rigid Point Cloud Registration (PCReg) refers to the problem of finding the rigid transformation between two sets of point clouds. This problem is particularly important due to the advances in new 3D sensing hardware, and it is challenging because neither the correspondence nor the transformation pa…

Learning to Understand Image Blur

CVPR 2018poster

While many approaches have been proposed to estimate and remove blur in a photo, few efforts were made to have an algorithm automatically understand the blur desirability: whether the blur is desired or not, and how it affects the quality of the photo. Such a task not only relies on low-level visual…

Global localization by soft object recognition from 3D Partial Views

IROS 2015poster

Global localization is a widely studied problem, and in essence corresponds to the online robot pose estimation based on a given map with landmarks, an odometry model, and real robot sensory observations and motion. In most approaches, the map provides the position of visible objects, which are then…
