Our network mimics traditional feature based methods and estimates the homography in a coarse to fine manner, where the resolution of feature maps is progressively increased. 2021 ) first used a similar way in VPR to align two different views of a same place in the urban scene. We present a deep convolutional neural network for estimating the relative homography between a pair of images. On the other hand, previous deep homography approaches use either synthetic images for supervised learning or aerial images for unsupervised learning, both ignoring the importance of Apr 25, 2024 · The results, presented in Fig. While visual enhancement can improve contrast and clarity, it may introduce visual-tolerant artifacts that obscure the structural integrity of images.
