LDFE: Laplacian Decoupled Feature Enhancement Block for Dual-Stream CNN-based RGB-IR Object Detection
TL;DR
RGB-IR object detection faces challenges due to varying data modalities. A novel Laplacian Decoupled Feature Enhancement Block (LDFE) was developed to improve feature extraction in dual-stream convolutional neural networks (CNNs).
✦ Why It Matters
Implementing LDFE in dual-stream CNNs can enhance object detection capabilities in low-visibility environments today.
Key Takeaways
- Explore LDFE for improved feature fusion in your models.
- Utilize GS2E for noise suppression in main modalities.
- Apply LC2E for extracting fine-grained details in local features.
- Test performance improvements on datasets like M3FD and FLIR-Aligned.
How It Works
LDFE separates features into global and local components using a Laplacian Pyramid. The GS2E module enhances global features by suppressing noise through cross-modal attention and captures long-range dependencies.
Meanwhile, the LC2E focuses on local features, employing triple convolution to extract detailed information for effective fusion.
