precise edge detection of gravity anomalies by tilt angle filters
measurements of the tilt angle of potential fields can be a useful aid to their interpretation. there are several varieties of the methods in use, such as tilt angle, and the derivative of tilt angle. tilt angle filters are used for exact edge detection of the rectangular bodies artificially by writing a matlab code. the gravity effects of these models are computed by standard algorithms. the e...
متن کاملNew approaches to enhance chemotherapy in SCCHN.
Chemotherapy is the standard approach to the treatment of patients with recurrent and metastatic squamous cell carcinoma of the head and neck (SCCHN) and is also now a common component of treatment for patients with locoregionally advanced, non-metastatic disease. Cisplatin has for many years been the agent of choice, alone or in combination with other agents, particularly 5-FU. The advent of t...
متن کاملa new edge detection method based on the analytic signal of tilt angle (asta) for magnetic and gravity anomalies
in order to obtain maximum information from magnetic and gravity anomaly maps, application of an edgedetection method is necessary. in this regard two commonly used methods are derivative filters and local phase filters. in this paper, a matlab code is expanded to combine an analytic signal filter and a tilt angle filter as a new edge detection filter called asta filter. this method was demonst...
متن کاملبررسی های باستان سنجی در تپه حصار دامغان با استفاده از روش های گرانی سنجی و مغناطیس سنجی
Research and exploration of the remaining relics from the past has special importance in identifying the date, history and the identity of a country. Development and the advancement of human knowledge have offered new methods for the detection archaeological sites that by using them without the need for excavation and destruction of antiquities can be found useful information. Today, the non-de...
متن کاملEdge detection of gravity anomaly sources via the tilt angle, total horizontal derivative, total horizontal derivative of the tilt angle and new normalized total horizontal derivative
In this paper the application of edge detection techniques to gravity data are described. Edge enhancement in potential-field data helps geologic interpretation. There exist several methods for enhancing edges, such as tilt angle, and the derivative of tilt angle. Most of these methods are high-pass filters based on the horizontal or vertical derivatives of the field. To determine the filters n...
