Abstract
An apparatus for enhancing a 3-D image illuminated by a light source and having associated depth and texture information includes generating from the depth information a surface mesh having surface mesh sections. Texture sections corresponding to the surface mesh sections are determined from the texture information. The texture sections are ranked based upon their color intensity, and the characteristics of one or more light sources are adjusted to alter the color intensity of the ranked texture sections to thereby produce an enhanced image.
Claims32
An apparatus for enhancing a 3-D image, the 3-D image having depth and texture information associated therewith, the apparatus comprising:
- logic to generate, dependent at least in part upon the depth information, a 3-D mesh having surface mesh sections;
- logic to determine, dependent at last in part upon the texture information, texture sections corresponding to the surface mesh sections;
- logic to rank the texture sections and corresponding surface mesh sections dependent at least in part upon a color intensity of the texture sections;
- and
- logic to adjust the characteristics of one or more light sources to alter the color intensity of one or more of the color-intensity ranked texture sections to thereby produce an enhanced image.
At least one non-transitory machine readable medium having instructions stored therein that, in response to being executed on a device, cause the device to:
- extract depth and texture information associated with a 3-D image;
- generate from the depth information a surface mesh having surface mesh sections;
- determine from the texture information texture sections corresponding to the surface mesh sections;
- rank the texture sections and corresponding surface mesh sections in terms of their respective color intensity;
- and
- adjust the characteristics of one or more light sources to thereby alter the color intensity of one or more of the color-intensity ranked texture sections to produce an enhanced image.
A system, comprising:
- a central processing unit configured to execute stored instructions;
- and
- at least one memory device storing instructions readable by the central processing unit that, when executed by the central processing unit, are configured to:
- extract depth and texture information from a 3-D image;
- generate from the depth information a surface mesh having surface mesh sections;
- determine from the texture information texture sections corresponding to the surface mesh sections;
- rank the texture sections in terms of their respective color intensity;
- and
- adjust, add, or remove a characteristic of one or more light sources to thereby alter the color intensity of the one or more of the color-intensity ranked texture sections to thereby produce an enhanced image.
