Infer Induced Sentiment of Comment Response to Video: A New Task, Dataset and Baseline

NeurIPS 2024poster

Existing video multi-modal sentiment analysis mainly focuses on the sentiment expression of people within the video, yet often neglects the induced sentiment of viewers while watching the videos. Induced sentiment of viewers is essential for inferring the public response to videos and has broad appl…

Strategic Preys Make Acute Predators: Enhancing Camouflaged Object Detectors by Generating Camouflaged Objects

ICLR 2024poster

Camouflaged object detection (COD) is the challenging task of identifying camouflaged objects visually blended into surroundings. Albeit achieving remarkable success, existing COD detectors still struggle to obtain precise results in some challenging cases. To handle this problem, we draw inspiratio…

A Two-Branch Network for Video Anomaly Detection with Spatio-Temporal Feature Learning

ICASSP 2023accepted

Video anomaly detection is very challenging, as most anomalies are rare and inconclusive. Previous weakly supervised learning approaches utilize the classifier trained with video-level labels to locate anomalous clips from the video. However, the anomalous clips often contain both anomalies and nume…

Benchmarking Large Language Models on CMExam - A comprehensive Chinese Medical Exam Dataset

NeurIPS 2023poster

Recent advancements in large language models (LLMs) have transformed the field of question answering (QA). However, evaluating LLMs in the medical field is challenging due to the lack of standardized and comprehensive datasets. To address this gap, we introduce CMExam, sourced from the Chinese Natio…

Camouflaged Object Detection With Feature Decomposition and Edge Reconstruction

CVPR 2023poster

Camouflaged object detection (COD) aims to address the tough issue of identifying camouflaged objects visually blended into the surrounding backgrounds. COD is a challenging task due to the intrinsic similarity of camouflaged objects with the background, as well as their ambiguous boundaries. Existi…

Degradation-Resistant Unfolding Network for Heterogeneous Image Fusion

ICCV 2023poster

Heterogeneous image fusion (HIF) techniques aim to enhance image quality by merging complementary information from images captured by different sensors. Among these algorithms, deep unfolding network (DUN)-based methods achieve promising performance but still suffer from two issues: they lack a degr…

Weakly-Supervised Concealed Object Segmentation with SAM-based Pseudo Labeling and Multi-scale Feature Grouping

NeurIPS 2023poster

Weakly-Supervised Concealed Object Segmentation (WSCOS) aims to segment objects well blended with surrounding environments using sparsely-annotated data for model training. It remains a challenging task since (1) it is hard to distinguish concealed objects from the background due to the intrinsic s…

DVS-Voltmeter: Stochastic Process-Based Event Simulator for Dynamic Vision Sensors

ECCV 2022poster

"Recent advances in deep learning for event-driven applications with dynamic vision sensors (DVS) primarily rely on training over simulated data. However, most simulators ignore various physics-based characteristics of real DVS, such as the fidelity of event timestamps and comprehensive noise effect…

SECRET: Self-Consistent Pseudo Label Refinement for Unsupervised Domain Adaptive Person Re-identification

AAAI 2022technical

Unsupervised domain adaptive person re-identification aims at learning on an unlabeled target domain with only labeled data in source domain. Currently, the state-of-the-arts usually solve this problem by pseudo-label-based clustering and fine-tuning in target domain. However, the reason behind the…

Adversarial Unsupervised Domain Adaptation With Conditional and Label Shift: Infer, Align and Iterate

ICCV 2021poster

In this work, we propose an adversarial unsupervised domain adaptation (UDA) approach with the inherent conditional and label shifts, in which we aim to align the distributions w.r.t. both p(x|y) and p(y). Since the label is inaccessible in the target domain, the conventional adversarial UDA assumes…

Permutation-Invariant Feature Restructuring for Correlation-Aware Image Set-Based Recognition

ICCV 2019poster

We consider the problem of comparing the similarity of image sets with variable-quantity, quality and un-ordered heterogeneous images. We use feature restructuring to exploit the correlations of both inner&inter-set images. Specifically, the residual self-attention can effectively restructure the fe…
