A degraded image is an image that has reduced quality due to imperfections like noise and blur during capturing and recording, resulting in a loss of information and knowledge present in the original image. AI generated definition based on: Digital Image Enhancement and Reconstruction, 2023 ...
The Compton camera is an imaging device relevant for the detection of prompt photons produced during nuclear fragmentation in hadrontherapy. It allows a considerable improvement in detection compared to a standard gamma-camera but also requires more sophisticated image reconstruction techniques. In this ...
[22], morphological reconstruction and operations[19,23]for edge location refinement[24]are also used for segmentation. Other classical techniques for retinal image analysis involve Frangi’s filter[25], Gumbelprobability distribution function[26], locally adaptive derivative (LAD)[27], Hessian ...
The ability to reconstruct fine-resolution images in a high-count-rate environment is an ongoing challenge to the fields of nuclear security, medicine, and high energy physics. This study presents the characterization and performance of an image reconstruction algorithm and detector array in such an...

The obtained registration information is used for the image reconstruction. In the process of reconstruction, we utilize a multi-band fusion and exposure compensation method to output large-FOV and high-resolution image. GPU computing makes this process in parallel processing architecture, which allows...
MR image reconstruction has gained a tremendous far-reaching impact in the present technologically advanced world. The original problem will be bifurcated into two entities; L 1 norm and Total Variation (1,2). Eventually it can be effectively solved. It helps the expedite reconstruction of the ...
Fluorescence microscopy is a key driver of discoveries in the life sciences, with observable phenomena being limited by the optics of the microscope, the chemistry of the fluorophores, and the maximum photon exposure tolerated by the sample. These limits
