PURIFICATION BEFORE FUSION: TOWARD MASK-FREE SPEECH ENHANCEMENT FOR ROBUST AUDIO-VISUAL SPEECH RECOGNITION

ICASSP 2026poster

Audio-visual speech recognition (AVSR) typically improves recognition accuracy in noisy environments by integrating noise-immune visual cues with audio signals. Nevertheless, high-noise audio inputs are prone to introducing adverse interference into the feature fusion process. To mitigate this, rece…

Self-supervised Contrastive Pre-training for Dry Electrode EEG Emotion Recognition via Cross Device Representation Consistency

ICASSP 2025accepted

The use of dry electrode electroencephalography (EEG) systems holds significant importance in advancing the everyday application of emotion recognition. However, adapting it to real-world applications faces unique challenges due to low signal-to-noise ratios and unreliable emotion labels. To address…

CSOT: Cross-Scan Object Transfer for Semi-Supervised LiDAR Object Detection

ECCV 2024poster

"Large-scale 3D bounding box annotation is crucial for LiDAR object detection but comes at a high cost. Semi-supervised object detection (SSOD) offers promising solutions to leverage unannotated data, but the predominant pseudo-labeling approach requires careful hyperparameter tuning for training on…

Landmark-Guided Cross-Speaker Lip Reading with Mutual Information Regularization

COLING 2024main

Lip reading, the process of interpreting silent speech from visual lip movements, has gained rising attention for its wide range of realistic applications. Deep learning approaches greatly improve current lip reading systems. However, lip reading in cross-speaker scenarios where the speaker identity…
