TL;DR: In this paper, a scheme for interframe nonlinear adaptive prediction is proposed, where a quadratic operator, adapted pixel-by-pixel by an LMS technique, proves to be able to outperform conventional predictors when motion is present in the scene.

TL;DR: In this article, a linear combination of fourth-order moments is estimated by convolving the input signal with a quadratic 2-D filter and measuring the output power, and the performance of the structure is evi.dentiated by putting it to work both on natural and synthetic images.
Abstract: Fourth-order moments are proposed in this paper as tools for discerning different textures in an image. A linear combination of such statistics is shown to be estimated by convolving the input signal with a quadratic 2-D filter and measuring the output power. A method for designing suitable filters is proposed, and the performance of the structure is evi.dentiated by putting it to work both on natural and synthetic images.
