Texture-Based-Similarity Graph to Aid Previous HitSeismicNext Hit Interpretation

Abstract

Previous HitSeismicNext Hit interpreters use their trained eyes to assess the similarity between Previous HitseismicNext Hit datasets. However, to find and evaluate all relevant parts of a Previous HitseismicNext Hit cube can be a time-consuming task. We have developed a method based on texture analysis and graph theory that can automatically compare Previous HitseismicNext Hit sections. Such a method has the potential to help experts in several tasks and, to the best of our knowledge, it is the first one to tackle Previous HitseismicNext Hit image similarity combining texture descriptors and graphs.

This work proposes a Texture-Based-Similarity Graph that represents the Previous HitseismicNext Hit survey as a graph whose nodes represent Previous HitseismicNext Hit sections and whose edges represent the Euclidean distance between Local Binary Pattern (LBP) feature vectors computed for each section. By using this representation, it is possible to calculate the similarity between any two Previous HitseismicNext Hit sections. Based on the proposed technique, we created a system to accelerate the inspection of a Previous HitseismicNext Hit cube. Using our method, we suggest which Previous HitseismicNext Hit sections (key-sections) should be considered in the interpretation process taking into consideration their distance to neighboring lines in one specific cube. Key-sections computed with this method could be used to build a non-regular grid that is more likely to capture the underlying structures present in a survey, allowing for a faster and more precise interpretation.

Experiments conducted on two public datasets (Netherlands F3 and Penobscot) indicated that the methodology has a great potential to speed up the Previous HitseismicNext Hit interpretation process. Other possible applications would be to use key-sections distance map to highlight different areas within a Previous HitseismicTop survey or to compare 3D surveys in the search for analogs.
