Chaotic structures detecting in specific environment from seismic data by assigning multidirectional error to image point on which window is centered and calculating multidirectional errors to all image points of image block
Method of detecting chaotic structures in a given medium.It is of the type consisting in:calculating the components of the light intensity gradient vector E at every point of a window F, centered on a point of a block representative of the medium, and it is characterized in that it furthermore consists in summing elementary matrices M for all the points of the window F, diagonalizing said sum matrix A so as to determine its eigenvalues lambd1, lambd2, lambd3, quantifying, at the center of the window, the minimum of the said eigenvalues lambd1, lambd2, lambd3, and with the constraint UTxD=1, eliminating the contribution of the largest eigenvalue, defining a multidirectional error by integrating it in the plane defined by the eigenvectors corresponding to the remaining eigenvalues, assigning the multidirectional error to the image point on which the window F is centered, and calculating the multidirectional errors assigned to all the image points of the image block.
