WebJun 18, 2013 · This system includes two modules: (1) a feature extraction or “computing” module for estimating the oriented texture field from the raw image of the surface of a log; and (2) a scene analysis and detection module for analysing the oriented texture field. Basic principles of the system based on the gradient of the Gaussian filter have been given. WebThe local slope estimated from seismic images has a variety of meaningful applications. Slope estimation based on the plane-wave destruction (PWD) method is a widely accepted technique in the seismic community. However, the PWD method suffers from sensitivity to noise in the seismic data.

WebNov 1, 1997 · Tools from dynamical systems theory are used to decompose 3-D vector fields into simpler building blocks consisting of critical points and phase portraits. A robust critical point detector is developed for three dimensions. WebJan 1, 2006 · The performance of nonlinear structure tensors is demonstrated in three fields where the classic structure tensor is frequently used: orientation estimation, optic flow computation, and corner detection. In all these cases, the nonlinear structure tensors demonstrate their superiority over the classical linear one. tecnoriva srl
