Sentence examples for level constancy from inspiring English sources
The grey level constancy, that does not hold for surfaces with a non-Lambertian behaviour, can be extended for vector valued images with different image representations.
Variational correspondence models typically have two terms, the first one being a data term (e.g., based on the grey level constancy), while the second one is a regularisation term used to make the solution smooth.
For signal emitting nuclei motion that are represented by intensity pixels on MR images, the application of multi-resolution optical flow scheme that predicts fluid motion is based on grey-level constancy assumption or the optical flow constraint [33].
If HGT depends on the number of divisions undergone by a bacterium, then a certain level of constancy might be expected between the amount of exclusive DNA (i.e., DNA absent from other isolates) and the number of SNVs present; however, to the contrary, this ratio was highly variable and fluctuated from 29 (Ato210/PMC5,443 to 5,443 (PMA109.5/PMA37.5).
The variability in the features extracted using pixel-level colour constancy algorithms depend upon both the CCT of the illuminant and the sensors SNR.
One important conclusion from their work was that pixel-level colour constancy algorithms extract useful information from the responses of sensors whose spectral response covers a wavelength range of 80 nm or less [11].
Subsequently, Ratnasingam et al. [12] investigated the possibility of optimising the spectral responses of the image sensors to improve the quality of the illuminant invariant features that can be obtained from daylight illuminated scenes using pixel-level colour constancy algorithms.
This combined with the fact that the improvements in some cases are as large as 300% suggests that using ancillary information will significantly improve the ability to draw correct conclusions from the features from pixel-level colour constancy algorithms.
This observation suggests that if any information related to the probable illuminant spectrum is available then it might be possible to improve the interpretation of the features obtained from a pixel-level colour constancy algorithm.
The possible benefits of employing the phase of the day in conjunction with date information when identifying the possible source of a set of features obtained using a pixel-level colour constancy algorithm have been assessed using the measured daylight spectra [20].
Figure 3 shows a representative transient profiles of these feed composition for methane partial pressure ( (P_{{{text{CH}}_{ 4} }} ) ) 11.41 kPa and steam partial pressure ( (P_{{{text{H}}_{ 2} {text{O}}}} ) ) 22.82 kPa (i.e., S C = 2 1) at a temperature of 1073 K. Figure 3 displays methane conversion levels reaching constancy very early during reforming, which indicates steady-state condition.
