Abstract: Fusing visible and thermal imagery is a promising approach for robust object detection in challenging environments, taking advantage of the strengths from different spectral information. Building on previous work in static early fusion, we present a comparative study of adaptative reprojection fusion methods that exploit advanced projections and frequency-domain transforms to combine RGB and thermal data. We evaluate Principal Component Analysis, Factor Analysis, Wavelet and Curvelet-based fusion, all integrated into a YOLOv8 detection pipeline. Experiments are conducted on the LLVIP dataset, with a focus on methodological rigour and reproducibility. This research show promising results based on these methods comparing to previous early fusion methods. We discuss the implications for future research and the value of robust experimental design for advancing the state of the art in multispectral fusion.
