摘要:In recent years, more and more detector systems utilizing Compton scattering effect to detectgamma rays have been developed due to their potential for improved image sensitivity. However,the standard non-electron-tracking Compton based detectors can restrict the origin of the pho...

摘要:Abstract(#br)High-quality image reconstruction techniques allow the generation of high pixel density images from a set of low-resolution micrographs. In general, these techniques consist of two main steps, namely, accurate registration, and formulation of an appropriate forward image...

摘要:Images rendered by uncooled microbolometer-based infrared (IR) cameras are severely degraded by the spatial non-uniformity (NU) noise. The NU noise imposes a fixed-pattern over the true images, and the intensity of the pattern changes with time due to the temperature instabili...

摘要:Abstract(#br)This paper presents B-MFBD, a parallel hybrid of bispectrum speckle imaging (SI) and multi-frame blind deconvolution (MFBD) image reconstruction techniques for anisoplanatic, long horizontal path imaging. Our aimis to recover an enhanced version of a turbulence-cor...

摘要:... The image quality, the imaging time and the effects of noise of the new system are studied in detail. Based on the analysis, we find that by reasonably choosing the total sampling rate (TSR), the imaging time of the CS-FT is obviously shorter than that of the conventional FT ...

摘要:... The analysis is focused on the comparison of the information contained in the hologram before and after performing the spatial filtering of the zero diffraction order and the twin image. We show that in the Fourier transform of the recorded hologram the information of the ob...

摘要:Abstract(#br)The Shift-and-Add (SAA) technique is a simple mathematical operation developed to reconstruct, at high spatial resolution, atmospherically degraded solar images obtained from stellar speckle interferometry systems. This method shifts and assembles individual degraded...
