Summary:
Geological models can be seen as images reproducing prescribed spatial features. Some interactive tools are introduced, which allow modifying images while preserving their main spatial structures. A perturbation is performed by applying the same transformation in all regions similar to a selected pattern within the image. Two types of transformation are proposed, consisting in directly changing the value of the variable, or in local magnifications. These methods can be applied to categorical and continuous variables and are useful tools for improving the conditioning to hard and soft data.
