The second big category of advanced image and video processing methods is dealing with stereoscopic images. Stereoscopic images are usually shot either by two normal cameras positioned in parallel and only a few centimeters apart, or by stereoscopic cameras with two lenses and separate image sensors for each one. Either way, the lenses have a distance from each other that resembles the distance between the human eyes, and allows the camera(s) to shoot images that can be fused to simulate three-dimensional vision.
The need for the two fields of view leads to a subsequent doubling of the frame rate and storage space needs. This is because instead of showing just one image, modern 3-D televisions must display two images, one for the left and one for the right eye. Similarly, to store a 3-D video, we need to have double the space compared to a normal 2-D video.
Image registration is again the most significant aspect of 3-D image and video processing. The only way...
