In this paper we describe a new approach to shar p boundary geophy sical inversion. We demon strate that regularized inversion with a minimum support stabilizer can be implemented by using a specially designed nonl inear parametrization of the mode l parameters. Thi s parametrization plays the same role as transformation into the space of the weighted model(More)
In this paper a method for digital image orientation recognition is proposed. Feature vectors are chosen to be flip-invariant to effectively classify images onto portrait-oriented and landscape-oriented. A new texture feature is proposed based on the observation that more textured areas are located usually in the lower part of the image. The method was(More)
