SeaBeam

Figure 10 shows an image of deep seawater bottom in the Pacific of a sea-floor spreading center produced acoustically by a device called SeaBeam. Students here tried all three methods of filling empty bins on the this data using the Laplacian as a regularizer. From an interpretive point of view, differences among the three methods were minor and as expected, therefore, only one is shown in Figure 10.
