| Abstract: | In order to improve the imaging quality of ECT system,an imaging technique based on wavelet fusion method is proposed.Simulations are done by constructing an ECT sensor model using the finite element analysis software COMSOL.Conjugate gradient and singular value decomposition algorithms are utilized to implement image reconstruction,thereafter the wavelet-transform-based image fusion method is used in image processing.Both simulation and experimental results demonstrate that the proposed method can improve ... |
