ON THE USE OF MARKOV RANDOM FIELD IN GEOPHYSICALAPPLICATIONS: GELIBOLU PENINSULA

Journal Name:

Publication Year:

Abstract (2. Language): 
In this paper, Markov Random Field (MRF) approach is applied to gravity and magnetic anomaly map of Gelibolu Peninsula (Western Turkey) and complex fault structure of this region is modeled. We present a dynamic programming, MRF based on evaluation of noisy and super positioned effects of the various geological structures considering a statistical Maximum A Posteriori (MAP) criterion. We evaluate each pixel of N1 xN2 matrix using MRF approach, regarding the neighboring pixels and locality of their connections in real time with no priori processing. As synthetic examples, separation/ enhancement and edge detection performance of MRF is tested by various prism structures. After satisfactory results are found compared to classical derivative based approaches, as a real data, we have evaluated potential anomaly maps of Gelibolu Peninsula in the western region of Turkey.
Abstract (Original Language): 
Bu makalede Markov Random Field (MRF) yaklaşımı Gelibolu yarımadasının gravite ve magnetic anomalisine uygulanmış, karmaşık fay system modellenmiştir. Maksimum olabilirlik yaklaşımına uygun olan istatitik bir dinamik program olan MRF ile farklı yeraltı cisimlerinin gürültülü ve üstüste bindirilmiş halleri incelenmiştir. MRF, ön eğitim gerektirmeyen, komşuluk ilişki - sine dayalı reel zamanlı bir yaklaşımdır. Sentetik olarak farklı prizmaların oluşturduğu anomalilerin kenar ve ayrışımı gerçekleştirilmiştir. Klasik modellere gore üstünlüğü belirlendikten sonar, Gelibolu bölgesi anomalisi değerlendirilmiştir.
