Application of Blind Deblurring Reconstruction Technique to SPECT Imaging
An SPECT image can be approximated as the convolution of the ground truth spatial radioactivity with the system point spread function (PSF). The PSF of an SPECT system is determined by the combined effect of several factors, including the gamma camera PSF, scattering, attenuation, and collimator response. It is hard to determine the SPECT system PSF analytically, although it may be measured exp...
متن کاملPerformance Evaluation of FBP Reconstruction in SPECT Imaging
Introduction: The purpose of this study is to define the optimal parameters for the tomographic reconstruction procedure in a routine single photon emission tomography. The Hoffman brain phantom is modified to evaluate the reconstruction method. The phantom was imaged in a 3 and 2-dimensional conformation and the results were compared. Materials and Methods: The 2D phant...
متن کاملApplication of Krylov subspaces to SPECT imaging
The application of the conjugate gradient (CG) algorithm to the problem of data reconstruction in SPECT imaging indicates that most of the useful information is already contained in Krylov subspaces of small dimension, ranging from 9 (two-dimensional case) to 15 (three-dimensional case). On this basis, a new, proposed approach can be basically summarized as follows: construction of a basis span...
متن کاملImplementation of Deblurring Images Using Blind Deconvolution Technique
In Imaging science, Image processing is any form of signal processing for which the input is an image and the output may be either an image or set of characteristics or parameters related to the image. Sometimes,the images may be corrupted. Such degradations may be either due to motion blur, noise or camera misfocus. So, a classical research area called Image Restoration came into existence. Th...
متن کاملApplication of Blind Deblurring Algorithm for Face Biometric
Face recognition is one of the most important abilities which we use in public security and for identity verification for physical and logical access. It is well known that many image-based face recognition algorithms perform well, when constrained (frontal, well illuminated, high-resolution, sharp, and full) face images are acquired. However, their performance degrades signi?cantly when the te...
