Universal Guideline-Driven Image Clustering via a Hybrid LLM Agent

CVPR 2026

Unifying image clustering across different clustering scenarios remains challenging due to fundamental gaps among tasks. We introduce a Guideline-Driven Image Clustering Agent, the first universal framework that bridges these gaps through textual guidelines. To incorporate complex guidelines without

Efficient Fusion of Computationally Diverse Modalities Using Chunking and Cross-Attention

ICASSP 2025accepted

Emotion recognition is inherently a multimodal problem. Humans use both audible and visual cues to determine a person’s emotions. There has been extensive improvement in the methods we use to fuse audio and visual representations between two unimodal deep-learning models. However, there is a lack of…

Improving Lip-synchrony in Direct Audio-Visual Speech-to-Speech Translation

ICASSP 2025accepted

Audio-Visual Speech-to-Speech Translation (AVS2S) typically prioritizes improving translation quality and naturalness. However, an equally critical aspect in audio-visual content is lip-synchrony—ensuring that the movements of the lips match the spoken content—essential for maintaining realism in du…

Perceptual Evaluation of Audio-Visual Synchrony Grounded in Viewers’ Opinion Scores

ECCV 2024poster

"Recent advancements in audio-visual generative modeling have been propelled by progress in deep learning and the availability of data-rich benchmarks. However, the growth is not attributed solely to models and benchmarks. Universally accepted evaluation metrics also play an important role in advanc…

Learning Cross-Modal Audiovisual Representations with Ladder Networks for Emotion Recognition

ICASSP 2023accepted

Representation learning is a challenging, but essential task in audiovisual learning. A key challenge is to generate strong cross-modal representations while still capturing discriminative information contained in unimodal features. Properly capturing this information is important to increase accura…
