Improving the spatial resolution of magnetoencephalography images

The Methods of Improving of Spatial Resolution of Images

For wider include of CCD camera to industrial production as measurement device at present time defend mainly resolution of used CCD elements and for highresolution elements their price. At our department we developed the methods which allow to mathematically increasing the resolution of these CCD cameras.

Investigation of the effect of source distance and scattering medium on spatial resolution and contrast of Gamma camera images [Persian]

By identifying the effect of any parameter such as distance, attenuation and scattering on the Line Spread Function (LSF), one can compensate the quantitative and qualitative destructive effect of such parameters by deconvolution method. Using a 99mTC line source, this study was performed on a single head ADAC SPECT system operating in planar mode. Variation of FWTM and FWHM and LSFs as a...

Super-resolution of Defocus Blurred Images

Super-resolution is a process that combines information from some low-resolution images in order to produce an image with higher resolution. In most of the previous related work, the blurriness that is associated with low resolution images is assumed to be due to the integral effect of the acquisition device’s image sensor. However, in practice there are other sources of blurriness as well, inc...
