MaskLab: Instance Segmentation by Refining Object Detection with Semantic and Direction Features [PDF]

open access: yes2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2017
In this work, we tackle the problem of instance segmentation, the task of simultaneously solving object detection and semantic segmentation. Towards this goal, we present a model, called MaskLab, which produces three outputs: box detection, semantic ...

Beyond Tracking: Selecting Memory and Refining Poses for Deep Visual Odometry [PDF]

open access: yesComputer Vision and Pattern Recognition, 2019
Most previous learning-based visual odometry (VO) methods take VO as a pure tracking problem. In contrast, we present a VO framework by incorporating two additional components called Memory and Refining.
