Characteristic Scale in Satellite Images
2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings
Preserved Fulltext
We study the problem of finding the characteristic scale of a given satellite image. We want to define this feature so that it does not depend on the spatial resolution of the image. ...
Our approach is based on the use of a linear scale space and the total variation. The critical scale is defined as the one at which the normalized total variation is maximum. ...
In this paper, given an image, we aim at finding a characteristic scale which does not depend on the spatial resolution of the image. ...
