introduction: an efficient method of tomographic imaging in nuclear medicine is positron emission tomography (pet). compared to spect, pet has the advantages of higher levels of sensitivity, spatial resolution and more accurate quantification. however, high noise levels in the image limit its diagnostic utility. noise removal in nuclear medicine is traditionally based on fourier decomposition o...
Objective(s): A novel IQ-SPECTTM method has become widely used in clinical studies. The present study compares the quality of myocardial perfusion images (MPI) acquired using the IQ-SPECTTM (IQ-mode),conventional (180° apart: C-mode) and L-mode (90° apart: L-mode) systems. We assessed spatial resolution, image reproducibility and quantifiability using various physical phantoms. Materials and Me...
Scanning Impedance Microscopy (SIM) is one of the novel scanning probe microscopy (SPM) techniques, which has been developed to taking image from sample surface, providing quantitative information with high lateral resolution on the interface capacitance, and investigating the local capacitance–voltage (C–V) behavior of the interface and AC transport properties. The SIM is an ordinary AFM equip...
We present a novel method of Bayesian image super-resolution in which marginalization is carried out over latent parameters such as geometric and photometric registration and the image pointspread function. Related Bayesian super-resolution approaches marginalize over the high-resolution image, necessitating the use of an unfavourable image prior, whereas our method allows for more realistic im...
The super resolution means the quality of the image to the extent of the maximum capability of the technology referring it. The image capturing devices have their hardware limitations to reach to the perfection. A technique for Reconstruction of super resolution image using low resolution natural color image has been developed. The presented technique identifies local features of 1 / 4
During development of new and experimental imaging techniques, one must compare with other well established methods to qualify the validity of the new methods. The use of diffusion tensor magnetic resonance imaging for the visualization of collateral nerve fibers in the spinal cord was recently proposed. To validate this new imaging method, the MR results need to be compared with histology tiss...
This paper proposes high resolution RGB image supported near infrared (NIR) image super resolution method. In general, NIR image has low resolution characteristics. To show small image on bigger screen, super resolution method is applied to generate bigger image to fit the display. As CCD camera take colors images with high resolution, therefore one many extract helpful features for NIR image s...
Super Resolution (SR) image can be obtained from a set of Low Resolution (LR) images with noise and blur. The main object of Super Resolution is to get high resolution, high quality image from Low Resolution images. To remove the blur and noises caused by the imaging system as well as recover information, restoration techniques are used. Super resolution imaging processes one or more low resolu...
The island of Cephalonia, Western Greece, was struck by two strong seismic events, with magnitudes, ML= 5.8 and ML = 5.7 which occurred on Jan. 26, 2014 and Feb. 3, 2014 respectively. The first event was located near Argostoli’s town, whereas the second one was located at the north part of Livadi village. These two strong earthquake events followed by smaller aftershocks provoking extensive cru...
