Vectorized visibility is a powerful visibility representation for rendering direct illumination with all frequency quality. ...
With our method, we have more flexibility to manipulate the visibility functions in the favour of rendering speed and render the all frequency direct illumination twice as fast as the previous method. ...
Hence, our method can provide a 2x as fast rendering speed with a similar rendering quality w.r.t. the vectorized visibility method [12] . ...

It can be observed from Fig. 7 that though dehazed outputs using colour line [4] and haze line [6] produce visually pleasing results, the proposed method produces dehazed output with high visibility ...

Due its simplicity and high-quality performance, our scheme paves the way for the synchronization of long-distance quantum networks based on fibre, free-space, as well as hybrid solutions. ...
We test our scheme with a genuine quantum optical method in terms of the interference between two photons coming from two remotely synchronized sources spaced by distances of up to 100 km. ...
Compared to other reported solutions, our fully-optical method offers high synchronisation quality without the need for complex clock or control systems. ...

The results indicate that the visibility of flicker distortions is strongly reduced when the speed of coherent motion is large, and the effect is more pronounced when the video quality is poor. ...
Forty three naïve subjects participated in two tasks ("follow the moving object" and "view freely") and reported their percepts on 36 test videos. ...
When video quality was high, flicker visibility was low and less sensitive to motion, whereas when video quality was poor, the impact was large. ...
