Computing oriented texture fields

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.
