Abstract
In some embodiments left and right eye images are encoded following an entropy reduction operation being applied to one of the eye images when there is a difference between the left and right images of an image pair. Information about regions of negative parallax within the entropy reduced image of an image pair is encoded along with the images. Upon decoding a sharpening filter is applied to the image in an image pair which was subjected to the entropy reduction operation. In addition edge enhancement filtering is performed on the regions of the recovered entropy reduced image which are identified in the encoded image data as regions of negative parallax. Interleaving of left and right eye images at the input of the encoder combined with entropy reduction allows for efficient encoding, storage, and transmission of 3D images.
