Do you have content that you want converted from 2D to 3D? If so, then you will need to find a company that offers not only the best prices 2D to 3D conversion services, but also a high-quality final product. Finding such a company is not so easy today considering the fact that there are so many businesses offering this service. To stand a better chance of finding a firm that will offer you quality and affordable 2D to 3D conversion services, you need to have some basic knowledge on what this conversion is all about. For this reason, this article will provide you all the necessary information you need to know about 2D to 3D conversion.
Overview
2D to 3D conversion is done to add to your content, be it a video or image, the binocular disparity depth cue that the brain perceives. By doing this, the immersive effect of the content is improved as a person watches or views the converted content. For the immersive effect to come out correctly, the conversion has to be done in the right way. This means that the individual converting the content has to do it with sufficient accuracy and correctness. The individual should ensure that the disparity cue that he or she introduces does not contradict the other depth perception cues used by the brain, and the original 2D content is not deteriorated. If the conversion is done correctly, you will end up with a final product that is of high-quality.
There are two approaches to 2D-3D conversion. These approaches are automatic conversion usually used for VOD and 3DTV content, and semiautomatic conversion that is used for high-quality 3DTV and cinema content. We will discuss automatic conversion.
Automatic Conversion
Automatic conversion can be done using two methods. These methods are depth from focus and defocus and depth from perspective:
– Depth from focus and depth from defocus
Depth from focus, on the other hand, compares the range of images taken with focus distances that are different over the sharpness of an object to find out how far it is from the camera. Ten to fifteen images are needed for depth from focus to work. Depth from defocus is based on the fact that the mind perceives the depth of an image from the amount of blur it has. Two to three images are needed for this approach to work.
– Depth from perspective
This method is based on the way the brain perceives parallel lines. When you see parallel lines such as railroad tracks, the brain perceives that the more the lines converge, the farther away they are.
Now there you go, some of the basic knowledge you should have on 2D to 3D conversion.
