Warping is one of the key areas of image analysis but there has been no understanding of the effects of different non-linear deformations in literature. This paper addresses the problem of the distortion effect produced by different types of non-linear deformation strategies on textured images. The images are modelled by a Gaussian random field. We first give various examples to illustrate that the model generates realistic images. We consider two types of deformations--a deterministic deformation and a landmark based deformation. The latter includes various radial basis type deformations including the thin-plate splines based deformation. The effects of deformations are assessed through Kullback
