Geometric correction of airborne scanner imagery by matching Delaunay triangles
TLDR
An algorithm is described which uses matching Delaunay triangles to achieve a form of geometric correction that can cope with high frequency distortion and has the capacity to correct images which exhibit very complex patterns of distortion.Abstract:
A major factor limiting the usefulness of airborne scanner imagery such as ATM has been the inability of conventional geometric correction procedures to remove high frequency distortion induced by platform and relief effects. An algorithm is described which uses matching Delaunay triangles to achieve a form of geometric correction that can cope with high frequency distortion. Early experimental results show that the procedure has the capacity to correct images which exhibit very complex patterns of distortion.read more

A spatial–temporal approach to monitoring forest disease spread using multi-temporal high spatial resolution imagery
TL;DR: This paper proposes a spatial–temporally explicit algorithm to classify individual images using the spectral and spatial-temporal information derived from multiple co-registered images, and showed that the improvement from the contributions of spatial—temporal contextual information indicated the importance of spatial– Temporal modeling in multi–temporal remote sensing in general and forest disease modeling in particular.
