2D to 3D conversion adds a binocular disparity depth cue to
digital images, which improves the immersive effect when viewing stereo video.
The process involves creating a depth map for each frame of the 2D video, which
is a grayscale image that shows the distance of each pixel from the camera. The
depth map is then used to shift each pixel of the 2D image to the left or right
to create the stereo video.
