PR0CEDE OF HIERARCHICAL DETERMINATION OF COHERENT EVENTS IN AN IMAGE

摘要

The method according to the invention concerns the determination of coherent events of a seismic image and it comprises the following operating phases: a phase of choice of a segmentation criterion according to a variable and at least one sliding window on said zone and its characteristics, - a hierarchical segmentation phase, for positions of the sliding window overlapping, comprising a segmentation of said zone into n regions and for each pixel identified at least once by a segmentation boundary, - an allocation phase to the non-marked pixels of a value of indices E1 and EIC corresponding to a non-numeric or alphanumeric characteristic value, - a phase of determining the coherent events of the image by thresholding the indices Ell and ECI c that is, selecting only pixels marked from the area corresponding to values below or above a set threshold. Ageries obtained by physical methods of seismic imaging: amplitude data or seismic attributes and also to medical imaging data, sonar, non-destructive testing of materials, etc.
