    Low-Resolution Target Detection with High-Frequency Information Preservation by Feng Zhang, Hongyang Bai, Wenlong Yin, Ze Li, Hailong Ma, Lei Chen

    Published 2024-12-01
    “…It is composed of two key components: (1) the decoupled high-frequency learning component, which extracts the high-frequency information along the vertical and horizontal directions separately, and (2) the dilated frequency-aware channel correlation component, which decomposes the input feature map into multiple smaller ones in a dilated manner, concatenates them by channel, and then correlates the combined channels in the frequency space. Our module can generally be integrated into existing network architectures for target detection (e.g., YOLO, HRNet). …”
