Reconstruction and enhancement of sea-bed topography by using 2-D signal processing
The application of 2D signal processing to profiles collected in airborne laser bathymetry is investigated. The processing involves a type of 2D filtering for the suppression of impulsive noise and the application of a sophisticated 2D interpolation technique for the reconstruction of bathymetric data. The reconstructed profiles are further enhanced by two adaptive procedures: one involves 2D power spectral analysis of the data on a block-by-block basis and the other concerns the estimation of the data on a point-by-point basis. Results show that each type of filtering enhances the accuracy of bathymetric measurement quite significantly.<>
