Sentence examples for below the visibility threshold from inspiring English sources

The fainter rings are still far below the visibility threshold.

For medium luminance levels, the visibility threshold is generally small.

In other words, the visibility threshold may differ depending on the background luminance level.

However, the visibility threshold proposed in [8] mainly focused on the whole image distortion, rather than the effect of the image content and local features on the visibility threshold.

These differences were computed according to the visibility threshold, which was based on the background luminance levels.

Here, QPTAVT refers to the asymmetrical visibility threshold of the quantization parameters, revealing the visibility threshold for the right view with respect to the left view {mathrm{QP}}_{mathrm{TAVT}}={mathrm{QP}}_{mathrm{Th}}-{mathrm{QP}}_l.

For example, if the background luminance level is low, the visibility threshold generally has a relatively large value.

In [18], Safranek showed that the visibility threshold needs to be changed based on the background luminance.

The vertical straight line at 1 µmol/L corresponds to the visibility threshold of the dye by the experimenters.

The detection sensitivity is much lower than the eye visibility threshold, estimated at 300 nmol × L−1 on the same object.

In this paper, we applied the Paired Comparison Method (PCM) to study the asymmetrical visibility threshold.
