What are the limitations of traditional fusion strategies in gas detection

Traditional fusion strategies in gas detection face several limitations that hinder their effectiveness. One of the primary limitations is the oversimplified fusion of RGB and thermal modalities, which often leads to the loss of crucial information for detecting vision-invisible gases. These strategies fail to consider the unique characteristics of gases that are exclusively visible in thermal images, resulting in misclassifications and inaccurate detections. Moreover, traditional fusion techniques do not effectively address the challenges posed by the low-texture nature of thermal images, making it difficult to distinguish between gas regions and background noise. As a result, these strategies struggle to provide precise and reliable gas detection outcomes in real-world scenarios.

How does the RCA module in RT-CAN enhance the detection of vision-invisible gases

The RCA (RGB-assisted Cross Attention) module in RT-CAN significantly enhances the detection of vision-invisible gases by addressing the limitations of traditional fusion strategies. The RCA module facilitates the fusion of RGB and thermal features by leveraging cross-attention mechanisms, allowing the model to focus on relevant information from both modalities. This approach enables the model to effectively learn and distinguish gas regions from background noise in thermal images. By incorporating rich information from RGB images to assist the thermal modality, the RCA module enhances the model's ability to accurately detect gases that are invisible to the human eye. This innovative fusion strategy improves the overall performance of RT-CAN in gas detection tasks, making it a more effective and reliable solution for detecting vision-invisible gases.
