Abstract
The invention concerns a method for detecting geological discontinuity in an environment using an optical flow. The method includes the steps of selecting in the seismic block a section containing at least one discontinuity. The section constitutes a seismic image. The method includes computing a rough optical flow on the seismic image to obtain a first representation of an optical flow wherein the discontinuity constitutes a moving front. The method also includes smoothing, by a non-supervised dynamic cluster process, the optical flow representation so as to obtain a second optical flow representation wherein the discontinuity shows accentuated contrasts.
Claims5
Method of detecting a geological discontinuity in a seismic block, characterized in that it consists in:
- selecting within the seismic block at least one section comprising at least one discontinuity, said section constituting a seismic image,
- calculating a raw optical flow over said seismic image so as to obtain a first representation of the optical flow, in which the discontinuity constitutes a moving front, and in,
- smoothing said representation of the optical flow by unsupervised dynamic clusters so as to obtain a second representation of the optical flow, in which said discontinuity exhibits enhanced contrasts.
