Bidirectional Domain Mixup for Domain Adaptive Semantic Segmentation

AAAI 2023technical

Mixup provides interpolated training samples and allows the model to obtain smoother decision boundaries for better generalization. The idea can be naturally applied to the domain adaptation task, where we can mix the source and target samples to obtain domain-mixed samples for better adaptation. Ho…

A Self-Supervised Sampler for Efficient Action Recognition: Real-World Applications in Surveillance Systems

RA-L 2022

The common paradigm of CNN-based action recognition modelsis to simply use the average of the dense predictions from every frame. However, these dense predictions are inefficient since all frames are evenly utilized regardless of the existence of the action. In real-time action recognition applicati

PT4AL: Using Self-Supervised Pretext Tasks for Active Learning

ECCV 2022poster

"Labeling a large set of data is expensive. Active learning aims to tackle this problem by asking to annotate only the most informative data from the unlabeled set. We propose a novel active learning approach that utilizes self-supervised pretext tasks and a unique data sampler to select data that a…

OCR-based Inventory Management Algorithms Robust to Damaged Images

ICRA 2021poster

Accurate and fast inventory management algorithms are essential in the modern distribution industry. However, the configuration process of inventory management algorithms is very expensive, and the direct comprehensive management of inventory procedures is labor intensive and inaccurate. Therefore,…

Vision system and depth processing for DRC-HUBO+

ICRA 2016

This paper presents a vision system and a depth processing algorithm for DRC-HUBO+, the winner of the DRC finals 2015. Our system is designed to reliably capture 3D information of a scene and objects and to be robust to challenging environment conditions. We also propose a depth-map upsampling metho
