Multiscalar stereo video format conversion

摘要

Techniques for converting 3D images using alpha maps are described. A left-view image and a right-view image may be determined from media data received by a 3D display system. An alpha map specifying a plurality of operations for a plurality of locations that correspond to the first plurality of locations in the images may also be determined. The plurality of operations specified in the alpha map may be applied by the 3D display system to process the left-view and right-view images, and to generate, based on the left-view and right-view images, a third image in an appropriate 3D format.

1. A method comprising:
determining a first image comprising a first plurality of picture elements for a first plurality of locations in the first image; determining a second image comprising a second plurality of picture elements for a second plurality of locations in the second image; determining a first alpha map specifying a plurality of operations for a plurality of locations that correspond to the first plurality of locations in the first image and the second plurality of locations in the second image; applying the plurality of operations specified in the first alpha map to generate a third image comprising a third plurality of picture elements for a third plurality of locations in the third image, a picture element in the third plurality of picture elements being generated in an operation in the plurality of operations, the operation being for a location in the plurality of locations, the location in the plurality of locations corresponding to a first location in the first plurality of locations in the first image and a second location in the second plurality of locations in the second image; determining a fourth image comprising a fourth plurality of picture elements for a fourth plurality of locations in the fourth image; determining a second alpha map specifying a plurality of second operations for a plurality of second locations that correspond to the third plurality of locations in the third image and the fourth plurality of locations in the fourth image; and applying the plurality of second operations specified in the second alpha map to generate a fifth image comprising a fifth plurality of picture elements for a fifth plurality of locations in the fifth image, wherein a picture element in the fifth plurality of picture elements is generated in a second operation in the plurality of second operations, wherein the second operation is for a location in the plurality of second locations, and wherein the location in the plurality of second locations corresponds to a third location in the third plurality of locations in the third image and a fifth location in the fifth plurality of locations in the fifth image, wherein the method is performed by one or more devices comprising a processor.
