Abstract:
1. A computer-implemented method for converting a 2-dimensional (2D) image to 3-dimensional (3D) stereo images comprising: determining sharpness values for individual pixels of a 2D input image; performing a first region-based sampling of the sharpness values to determine a first plurality of sample sharpness values and a second region-based sampling of the sharpness values to determine a second plurality of sample sharpness values, wherein the first and second region-based samplings are performed at different resolutions; scaling the first plurality of sharpness values to generate a first plurality of scaled sharpness values and the second plurality of sharpness values to generate a second plurality of scaled sharpness values; smoothing the first plurality of scaled sharpness values to generate a first plurality of smoothed sharpness values and the second plurality of scaled sharpness values to generate a second plurality of smoothed sharpness values; determining a first plurality of interpolated sharpness values based on the first plurality of smoothed sharpness values and a second plurality of interpolated sharpness values based on the second plurality of smoothed sharpness values; and merging the first plurality of interpolated sharpness values and the second plurality of interpolated sharpness values to generate a depth map having a plurality of depth values associated with the 2D input image.
