Rank-based Geographical Regularization: Revisiting Contrastive Self-Supervised Learning for Multispectral Remote Sensing Imagery Self-supervised learning (SSL) has become a powerful paradigm for learning from large, unlabeled datasets, particularly in computer vision (CV). However, applying SSL to multispectral remote sensing (...

GeoRank is a novel regularization method for contrastive self-supervised learning ( #SSL ) applied to #multispectral remote sensing imagery.

Bare-rooted trees all look dead in winter… but are they?
Using infrared photography, you can spot living tissue weeks before buds break.
Visible light lies. Near-IR tells the truth.

Image of finger clip with apertures for light, hyperspectral camera (HSC) and spectrometer. A scheme, indicating that the computer analyzes the combined signals from the HSC and spectrometer. A graph, indicating a good correlation (k=0.92) between the true and predicted values of HGB-Model 3 in blood. Text Box: Conclusion: Spectrometers have low amplitude resolution and accuracy, while HSPs suffer from limited number of wavelength channels. To solve this, we propose a method of acquiring spectrometer data combined with HSP and modelling the data. This combines the advantages of both, and effectively improves the accuracy of the non-invasive blood components measurements.
