Low powered (10× objective) images of 3.5 mg/kg Hg2+-treated animals (Fig. 4I) show that the ethidium-labeling was confined to the renal cortex, and outer medulla, but was absent in the inner medulla (arrow) these results are in agreement with previous studies showing that the proximal tubules are the primary site of Hg2+ toxicity [ 30, 31, 35].
To measure and compare the objective image quality of true noncontrast (TNC) images with virtual noncontrast (VNC) images acquired by tin-filter enhanced, dual-source, dual-energy computin-filter enhancedT) of upper abdomen.
Considering that technical advancements are an essential part of the increasing CAD detectability on chest CT scans, secondary endpoints will include the subjective and objective image quality of utilised standard chest CTs, in combination with radiation dose and administered contrast material volume.
In Figure18, charts can be found visualising the averaged values of the objective image metrics for this mode of encryption using the images of the Kodak IDB.
The development of objective image quality assessment (IQA) metrics aligned with human perception is of fundamental importance to numerous image-processing applications.
However, we have pointed out how each of the algorithms has been evaluated by the own authors: subjectively (by visual inspection) or objectively (by the implementation of an objective image quality measure).

Three measure classes, i.e., full-reference (FR), reduced-reference (RR) and no-reference (NR) exist in the area of objective image quality assessment.
