Faults Detection

Introduction

This work is focused for automatic enhancement and identification of the active sea faults [1-2], usually connected with seismic activity using bathymetric images. (see Figure 1).

Experimental results are presented on several real images demonstrating the high-performance of the proposed scheme [1-2].

Methodology

Figure 2: Scheme of the proposed system architecture [1]. Figure 3: Scheme of the proposed system architecture [2].

According to the proposed method, first, we compute the Slope and Aspect images [1-2]. Then, a rotation and scale invariant filter and a pixel labeling method provide an enhancement of the sea faults and a detection of points that probably belong on them, respectively [1-2]. The enhancement and detection results are efficiently combined to construct a weighted graph that represents the possible fault points and the connections between them taking into account the shape and topology of faults [2].
