Image fusion is a method for obtaining a highly informative image by merging the relative information of an object obtained from two or more image sources of the same scene. The satellite cameras give a single band panchromatic (PAN) image with high spatial information and multispectral (MS) image with more spectral information. The problem exists today is either PAN or MS image is available fr...

Introduction: The limited resolution of the imaging system causes partial volume effects (PVEs). These results in spreading of image counts to the neighboring pixels. This phenomenon is called spill-out effect. This study aimed at quantifying PVEs using ImageJ. Methods:Technetium-99m solution of concentration of 74 kBq/ml was filled into spheres A, B<...

AbstractDespite achieving remarkable progress in recent years, single-image super-resolution methods are developed with several limitations. Specifically, they trained on fixed content domains certain degradations (whether synthetic or real). The priors learn prone to overfitting the training configuration. Therefore, generalization novel such as drone top view data, and across altitudes, is cu...

Single image super-resolution (SISR), as a traditional ill-conditioned inverse problem, has been greatly revitalized by the recent development of convolutional neural networks (CNN). These CNN-based methods generally map low-resolution to its corresponding high-resolution version with sophisticated network structures and loss functions, showing impressive performances. This paper provides new i...

polymer gel dosimeter is the only accurate three dimensional (3d) dosimeter that can measure the absorbed dose distribution in a perfect 3d setting. gel dosimetry by using optical computed tomography (oct) has been promoted by several researches. in the current study, we designed and constructed a prototype oct system for gel dosimetry. first, the electrical system for optical scanning of the g...
