Tsanet: Temporal and Scale Alignment for Unsupervised Video Object Segmentation

no code implementations8 Mar 2023 Seunghoon Lee, Suhwan Cho, Dogyoon Lee, Minhyeok Lee, Sangyoun Lee

In recent works, two approaches for UVOS have been discussed that can be divided into: appearance and appearance-motion-based methods, which have limitations respectively.

RT-MOT: Confidence-Aware Real-Time Scheduling Framework for Multi-Object Tracking Tasks

no code implementations19 Oct 2022 Donghwa Kang, Seunghoon Lee, Hoon Sung Chwa, Seung-Hwan Bae, Chang Mook Kang, Jinkyu Lee, Hyeongboo Baek

Focusing on multiple choices of a workload pair of detection and association, which are two main components of the tracking-by-detection approach for MOT, we tailor a measure of object confidence for RT-MOT and develop how to estimate the measure for the next frame of each MOT task.

Unsupervised Video Object Segmentation via Prototype Memory Network

1 code implementation8 Sep 2022 Minhyeok Lee, Suhwan Cho, Seunghoon Lee, Chaewon Park, Sangyoun Lee

The proposed model effectively extracts the RGB and motion information by extracting superpixel-based component prototypes from the input RGB images and optical flow maps.

Pixel-Level Equalized Matching for Video Object Segmentation

no code implementations4 Sep 2022 Suhwan Cho, Woo Jin Kim, MyeongAh Cho, Seunghoon Lee, Minhyeok Lee, Chaewon Park, Sangyoun Lee

Feature similarity matching, which transfers the information of the reference frame to the query frame, is a key component in semi-supervised video object segmentation.

Bayesian AirComp with Sign-Alignment Precoding for Wireless Federated Learning

no code implementations14 Sep 2021 Chanho Park, Seunghoon Lee, Namyoon Lee

In this paper, we present a simple yet effective precoding method with limited channel knowledge, called sign-alignment precoding.

Bayesian Federated Learning over Wireless Networks

no code implementations31 Dec 2020 Seunghoon Lee, Chanho Park, Song-Nam Hong, Yonina C. Eldar, Namyoon Lee

This paper proposes a Bayesian federated learning (BFL) algorithm to aggregate the heterogeneous quantized gradient information optimally in the sense of minimizing the mean-squared error (MSE).
