Integration of Contextual Knowledge in Unsupervised Subpixel Classification: Semivariogram and Pixel-Affinity Based Approaches

, 2018
This letter investigates the use of coarse-image features for predicting class labels at a given finer spatial scale. In this regard, two unsupervised subpixel mapping approaches, a semivariogram method, and a pixel-affinity based method are proposed ...

The influence of the choice of a semivariogram model on interpolation results of mineral deposits parameters

, 2009
In the paper the influence of the choice of a semivariogram model on interpolation results of mineral deposits parameters has been characterized. For the lack of knowledge of real variability of the variables on small distances, the nugget effect is ...
