Sentence examples for changes of contrast from inspiring English sources

Quantitative techniques for assessment of bowel wall vascularisation by CEUS can determine changes of contrast agent enhancement, reflecting the response of intestinal inflammatory disease to therapy at follow-up (Fig. 16).

Image adjustments such as changes of contrast and brightness were applied equally across the entire image.

Figure 3 shows the changes of contrast sensitivity in spatial frequencies of 6 and 12 cycles per degree (CPD) with and without glare over time.

In accordance with previous experiments based on more artificial motion sequences (Maddess and Laughlin, 1985; Kurtz et al., 2009; Liang et al., 2008; Liang et al., 2011), our results suggest that response changes evoked by discontinuities of the stimulus parameters, like transient changes of contrast, velocity or motion direction, are accentuated by adaptation.

In particular, it exploits the link between the change of contrast (as the resolution is increased) and the local Lipschitz regularity of the image [19, 20].

After the application of an adaptive technique of contrast enhancement that exploits the link between local Lipschitz image regularity and the change of contrast, a global power-law correction is performed.

In the second stage, the link between the local Lipschitz regularity and the change of contrast of the image across scales is exploited; after this stage, adaptive contrast enhancement can be performed on the faded image.

Further studies should evaluate any change of contrast enhancement pattern after treatment of focal lesions and perihepatic lymphadenopathy [ 27].

The false positives may arise due to transition of illumination or a change of contrast in the preparation of the samples.

Also, a recent neurophysiological study by Williford and Maunsell (2006) found that attention does not necessarily result in a change of contrast gain of area V4 neurons.

T1, T2, perfusion and diffusion imaging may all play a role as they all reflect the tissue thermal coagulation as a change of contrast[ 26 ].
