• Authors: Pranjay Shyam, Antyanta Bangunharcana and Kyung-Soo Kim
• Abstract summary: Poor image quality in low light images may result in a reduced number of feature matching between images. We show that even in low light images, feature matching using traditional hand-crafted feature detectors still performs reasonably well. Applying Low Light Image Enhancement (LLIE) algorithms can improve feature matching even more when paired with the right feature extraction algorithm.

• Abstract: Poor image quality in low light images may result in a reduced number of feature matching between images. In this paper, we investigate the performance of feature extraction algorithms in low light environments. To find an optimal setting to retain feature matching performance in low light images, we look into the effect of changing feature acceptance threshold for feature detector and adding pre-processing in the form of Low Light Image Enhancement (LLIE) prior to feature detection. We observe that even in low light images, feature matching using traditional hand-crafted feature detectors still performs reasonably well by lowering the threshold parameter. We also show that applying Low Light Image Enhancement (LLIE) algorithms can improve feature matching even more when paired with the right feature extraction algorithm.

  We propose an Adaptive Multi-scale Fusion network (AMFusion) with infrared and visible images. First, we separately fuse spatial and semantic features from infrared and visible images, where the former are used for the adjustment of light distribution. Second, we utilize detection features extracted by a pre-trained backbone that guide the fusion of semantic features. Third, we propose a new illumination loss to constrain fusion image with normal light intensity.

  Low-Light Image Enhancement (LLIE) techniques have made notable advancements in preserving image details and enhancing contrast. These approaches encounter persistent challenges in efficiently mitigating dynamic noise and accommodating diverse low-light scenarios. We first propose a method for estimating the noise level in low light images in a quick and accurate way. We then devise a Learnable Illumination Interpolator (LII) to satisfy general constraints between illumination and input.
