The visual quality assessment approaches and their classification are introduced. Recent developments on both image and video quality metrics, as well as several publicly available databases for both images and videos, are reviewed. Then, we conduct experiments on image and video quality databases to compare the performance of some existing state-ofthe-art visual quality metrics. It is shown th...

conclusion osem3d may provide better image quality and higher contrast than other methods for small animal imaging with the new myocardial imaging agent, [18f] fptp. results the location and size of myocardial infarction on pet images correlated closely with that observed with ttc staining. among the four reconstruction methods, osem3d provided the best assessment of infarct size (r2 = 0.994, p...

This article proposes a real-time test and verification system for full-reference automatic image quality assessment and verification of digital TV sets. Digital camera is used for acquisition of the TV screen content in order to ensure quality assessment of the content as perceived by the user. Test has been executed in three steps: image acquisition by camera, TV screen content extraction and...

Fingerprint quality assessment (FQA) has been a challenging issue due to a variety of noisy information contained in the samples, such as physical defect and distortions caused by sensing devices. Existing studies have made efforts to find out more suitable techniques for assessing fingerprint quality but it is difficult to achieve a common solution because of, for example, different image sett...

Image fusion is a tool that serves to combine multi sensors images by using advanced image processing techniques. Particularly it serves best in medical diagnosis i.e. computed tomography (CT), magnetic resonance image (MRI), scan provides different types of information, by fusing them we can get accurate information for better clinical diagnosis. Transform domain image fusion methods such as w...

This paper scrutinize image quality assessment emanate from discrete wavelet transform. Image quality assessment endeavor to procure visual quality metric dovetail deftly with human visual cognizance. Full reference IQA technique juxtaposes a reference and distorted image and prognosticate ocular quality. This technique schleps out by discerning contrariety between empirical score with image im...
