A computer implemented method for processing a seismic image comprising seismic values obtained from seismic measurements performed on a geological formation includes determining a seismic dip image based on the seismic image, said seismic dip image comprising local seismic dips representative of the local gradient of the seismic values of the seismic image; initializing a seismic horizon surface modeled by using a combination of spline functions or by using a triangle mesh; and iteratively modifying coefficients used for combining the spline functions, thereby iteratively modifying the seismic horizon surface to progressively increase alignment between local orientations of the seismic horizon surface and the corresponding local seismic dips, until a predetermined stop criterion is satisfied.
