Method and apparatus for processing three-dimensional (3d) image

An apparatus for processing a three-dimensional (3D) image, the apparatus comprising:

• a camera configured to acquire a frame of a color image and a frame of a depth image;
• a memory configured to store the acquired frame of the color image and the acquired frame of the depth image;
• and
• a processor configured to generate a frame by combining the acquired frame of the color image with the acquired frame of the depth image,
• wherein the processor is configured to combine a line of the acquired frame of the color image with a corresponding line of the acquired frame of the depth image.

A method for processing a three-dimensional (3D) image, the method comprising:

• acquiring a frame by combining a line of a color image with a line of a depth image;
• splitting a single line of the color image into a plurality of lines according to depth levels;
• performing a primary Fourier transform on the plurality of lines;
• generating a single added line by adding transformed lines obtained as a result of the performing the primary Fourier transform;
• and
• performing a secondary Fourier transform on the single added line.
