Unsupervised Intrinsic Image Decomposition With LiDAR Intensity

CVPR 2023poster

Intrinsic image decomposition (IID) is the task that decomposes a natural image into albedo and shade. While IID is typically solved through supervised learning methods, it is not ideal due to the difficulty in observing ground truth albedo and shade in general scenes. Conversely, unsupervised learn…

Discontinuous and Smooth Depth Completion With Binary Anisotropic Diffusion Tensor

RA-L 2020

We propose an unsupervised real-time dense depth completion from a sparse depth map guided by a single image. Our method generates a smooth depth map while preserving discontinuity between different objects. Our key idea is a Binary Anisotropic Diffusion Tensor (B-ADT) which can completely eliminate

Adaptive Loss Balancing for Multitask Learning of Object Instance Recognition and 3D Pose Estimation

IROS 2019poster

Object instance recognition and 3D pose estimation are important elements in robot vision technology. State-of-the-art methods improve the accuracy of both instance recognition and pose estimation using multitask learning. These methods use unified balancing parameters to integrate the loss of each…

Weakly Supervised Instance Segmentation Using Hybrid Networks

ICASSP 2019accepted

Weakly-supervised instance segmentation, which could greatly save labor and time cost of pixel mask annotation, has attracted increasing attention in recent years. The commonly used pipeline firstly utilizes conventional image segmentation methods to automatically generate initial masks and then use…

Unsupervised Object Proposal Using Depth Boundary Density and Density Uniformity

IROS 2018poster

Object proposal that detects candidate bounding boxes of objects in images is an effective way of accelerating object recognition in the robot/computer vision area. We propose an accurate and fast object proposal method using depth images. Existing proposal methods can be roughly divided into two ca…
