Tools for immersive video experience.

ExtVid

ExtVid is the tool for immersive video experience using OpenCV.

You can make your favorite video files more immersive.

Only thing you need to have is an input video file.

Background & How it works

Immersion for viewing video is strongly related with FoV (Field of View).

"When a viewer’s entire field of view is filled, it creates a more immersive experience, increasing their enjoyment of the content." L. Turban, F. Urban and P. Guillotel, "Extrafoveal Video Extension for an Immersive Viewing Experience," in IEEE Transactions on Visualization and Computer Graphics, vol. 23, no. 5, pp. 1520-1533, 1 May 2017, doi: 10.1109/TVCG.2016.2527649

But view angle of content should be under 45 angle, because of limitation of human fovea.

"The ideal picture size is defined for movie theatre for a horizontal viewing angle of 45 degrees at the prime seat." Lee YC.N., Shan LT., Chen CH. (2013) System Development of Immersive Technology Theatre in Museum. In: Shumaker R. (eds) Virtual, Augmented and Mixed Reality. Systems and Applications. VAMR 2013. Lecture Notes in Computer Science, vol 8022. Springer, Berlin, Heidelberg. doi: https://doi.org/10.1007/978-3-642-39420-1_42*

So best solution for immersive video experience is extending video by context matched image, as below.

ExtVid makes the video extended by context matched image.

Requirement

• Resolution can be divided by 4 (e.g. 1280x720)
