Method and apparatus for two-dimensional to three-dimensional image conversion

摘要

A method and apparatus provide two-dimensional to three-dimensional image conversion. The apparatus can include an input configured to receive a first image. The apparatus can include a controller configured to segment the first image into a plurality of regions, configured to perform a Fast Fourier Transform on at least one of the regions, and configured to determine a relative horizontal displacement distance between a first frame and a second frame of at least one region based on performing the Fast Fourier Transform.

1. A method comprising:
receiving a first image; segmenting the first image into a plurality of regions, each region of the first image comprising a frame; performing, on a first region of the plurality of regions, the first region comprising a first frame, a Fast Fourier Transform that comprises summing high frequency coefficients of averaged Fast Fourier Transform spectra of the first region to provide a summed high frequency coefficient of the first region; determining, from the summed high frequency coefficient of the first region and a summed high frequency coefficient of a second region, a largest summed high frequency coefficient; using a ratio of the largest summed high frequency coefficient to the summed high frequency coefficient of the first region, determining a horizontal displacement distance for the first region; generating a second image, the second image also comprising the plurality of regions, wherein a first region of the second image corresponds to the first region of the first image, and wherein the first region of the second image comprises a second frame, the second frame being a copy of the first frame displaced by the determined horizontal shift; and creating a stereoscopic image by combining the first frame and the second frame.
