This article describes a new approach to perform image segmentation. First an image is locally modeled using a spatial autoregressive model for the image intensity. Then the residual autoregressive image is computed. This resulting image possesses interesting texture features. The borders and...

The paper gives explicit formulas for the first moments of a sample codispersion coefficient defined as a suitably normalized sum of products of increments for time or space sequences. Derived formulas allow for the optimal choice of the lag in several spatial and temporal models and lead to...
