Electromagnetic Field Visualization by Image Processing
نویسندگان
چکیده
An inverse approach is applied for image improving during visualization of electromagnetic fields. The red, green, blue color (RGB) model is used. The RGB color sources have been evaluated using the RGB color distributions of the electromagnetic field data set. The Generalized Sampled Pattern Matching method is applied to solve an ill posed linear system of equations for the corresponding inverse problem. The new color distributions is generated and visualized using the obtained color sources. The images obtained during the electromagnetic field visualization of the most commonly used sensor coils are used and essentially improved.

CUDA-OpenGL Interoperability to Visualize Electromagnetic Fields Calculated by FDTD
─ In this contribution, a compute unified device architecture (CUDA) implementation of a two-dimensional finite-difference time-domain (FDTD) program is presented along with the OpenGL interoperability to visualize electromagnetic fields as an animation while an FDTD simulation is running. CUDA, which runs on a graphics processing unit (GPU) card, is used for electromagnetic field data generati...
متن کاملApproximate resistivity and susceptibility mapping from airborne electromagnetic and magnetic data, a case study for a geologically plausible porphyry copper unit in Iran
This paper describes the application of approximate methods to invert airborne magnetic data as well as helicopter-borne frequency domain electromagnetic data in order to retrieve a joint model of magnetic susceptibility and electrical resistivity. The study area located in Semnan province of Iran consists of an arc-shaped porphyry andesite covered by sedimentary units which may have potential ...
متن کاملSegmentation Assisted Object Distinction for Direct Volume Rendering
Ray Casting is a direct volume rendering technique for visualizing 3D arrays of sampled data. It has vital applications in medical and biological imaging. Nevertheless, it is inherently open to cluttered classification results. It suffers from overlapping transfer function values and lacks a sufficiently powerful voxel parsing mechanism for object distinction. In this work, we are proposing an ...
متن کاملInteractive Visualization for Image Guided Medialization Laryngoplasty
Surgical procedures require the physician to use preoperative and intra-operative information for deciding the optimal course of action to be taken on the patient. Medical visualization techniques are used to ‘guide’ the surgeon during the procedure to improve accuracy. We are presenting a visualization approach for image guided medialization laryngoplasty. A brief background is provided to des...
