Sentence examples for ratio of luminance from inspiring English sources

From experimental results, the GICam-II can significantly save the power consumption by 38.5% when compared with previous one and 98.95% when compared with JPEG compression, while the average peak signal-to-noise ratio of luminance (PSNRY) is 40.73 dB.

This factor represents the ratio of the luminance difference and the luminance intensity.

The relative illumination (RI) curve shown in Fig. 15 is computed as the ratio of corner luminance to the center luminance.

Having obtained the mask image, the Retinex image can be calculated by the ratio of input luminance and image mask.

In profile A, the residual is represented as a ratio of the luminance of the HDR image and the tone-mapped image after inverse gamma correction.

We use full reference objective metrics peak signal-to-noise ratio of the luminance component (YPSNR) and mean structural similarity index (MSSIM) to evaluate the spatial consistency of virtual views.

It can be seen that as the rate for each sequence is increased, a higher peak signal to noise ratio of the luminance component (Y-PSNR) is attained, till the point where all enhancement layers are transmitted.

Then, for each DRY, the predominant sky-luminance distributions over Athens and Bratislava are identified, by using the methodology of Kittler et al., who corresponded the main sky conditions to 15 theoretical sky standards in diagrams of the ratio of zenith luminance to diffuse horizontal illuminance against solar altitude.

The removal of redundant, i.e. low frequency, information is an efficient coding strategy for a system with limited bandwidth, as shown for optimal spatio-temporal filters at high signal-to-noise ratio of bright luminance [10], [11].

The GluR4-immunoreactivity in puncta associated with the NK1r-positive cells was generally strong compared with that of other GluR4 puncta in the deep dorsal horn that were seen in these sections, and to quantify this we compared the ratio of pixel luminance values for GluR4 : GluR2 between these populations (see Materials and methods).

This operates by matching ratios of averaged luminance using a spatial face model adapted here to incorporate biological proportions (the golden ratio).
