Facial Expression Recognition Using Residual Masking Network
Automatic facial expression recognition (FER) has gained much attention due to its applications in human-computer interaction. Among the approaches to improve FER tasks, this paper focuses on deep architecture with the attention mechanism. We propose a novel Masking idea to boost the performance of CNN in facial expression task. It uses a segmentation network to refine feature maps, enabling the network to focus on relevant information to make correct decisions. In experiments, we combine the ubiquitous Deep Residual Network and Unet-like architecture to produce a Residual Masking Network. The proposed method holds state-of-the-art (SOTA) accuracy on the well-known FER2013 and private VEMO datasets. The source code is available at https://github.com/phamquiluan/ResidualMaskingNetwork.

Core Innovation: Residual Masking
Masking Idea A novel attention mechanism refining feature maps for FER.The paper introduces a novel 'Masking Idea' implemented via 'Masking Blocks', which are U-Net based localization networks. These blocks refine feature maps by generating an activation map (FM) that scores the importance of input feature map regions (FR), allowing the network to focus on crucial spatial information for accurate emotional expression classification.
Residual Masking Block Workflow
The Masking Block refines feature maps through a U-Net inspired architecture, enhancing the network's focus on key facial areas.

76.82% State-of-the-Art Ensemble AccuracyThe Residual Masking Network achieves a new state-of-the-art ensemble accuracy of 76.82% on the challenging FER2013 dataset, outperforming previous ensemble methods by 1%. This demonstrates significant advancement in facial expression recognition.
Real-Time Facial Expression Recognition for HCI
Scenario: An enterprise requires a robust and real-time facial expression recognition system for human-computer interaction applications, such as improving customer service bots or monitoring user engagement.
Challenge: Existing systems struggle with real-time performance and accuracy in diverse, in-the-wild conditions, leading to delayed responses or misinterpretations of user emotions.
Solution: Implementing the Residual Masking Network enables processing of 100 frames per second per face, ensuring immediate and accurate emotional classification. Its attention mechanism, focusing on critical facial regions like eyes and mouth, boosts precision even in complex scenarios.
Impact: The enterprise benefits from enhanced user experience through highly responsive and accurate emotion detection, enabling more empathetic and effective AI interactions, and opening new avenues for data analytics on emotional responses.
