Abstract
A method of converting two-dimensional image data to three-dimensional image data includes dividing the image data into blocks, performing motion estimation on the blocks to produce block-based motion vectors, applying a global motion analysis and a local motion analysis to the block-based motion vectors to generate motion-based depth, applying a global image model and a local image model to the block-based motion vectors to generate image-based depth, and generating a three-dimensional view by fusing the motion-based depth and the image-based depth. Other conversion methods are also included.
