The 3-D seismic volume with the final 3-D seismic maps present a great opportunity for image processing. The limited readable information in these maps can be increased by subsequent digital image processing. Techniques of image processing have been employed in numerous geophysical fields, especially in gravity and magnetics. A review of digital image processing techniques also evaluates their applicability to 3-D seismic map enhancement. Digital image spatial and frequency enhancement are introduced and evaluated on Sierra BC 3-D seismic data.
