Abstract

A method for inserting a logo into a stereo video image to generate an overlaid stereo image, the method comprising: detecting presence of stereo pictures in the video image and, when stereo pictures are detected, determining the 3D format of said stereo pictures, said 3D format being a stereo spatially multiplexed format; generating a stereo logo comprising stereo spatially multiplexed logo pictures including a representation of the logo, said stereo spatially multiplexed logo pictures being arranged in said 3D format; and combining the stereo logo and the video image to generate the overlaid stereo image in said 3D format.

First claim

The invention claimed is:

1. A method for inserting a logo into a video image to generate an overlaid image, the method comprising:
detecting a presence of stereo spatially interleaved pictures in the video image, the stereo spatially interleaved pictures for the video image being arranged in a spatially interleaved format;
auto-detecting the interleaved format by analyzing a plurality of selective characteristics in said images and determining if said characteristics exceed a threshold that identifies them as stereo images, wherein said analysis is done using an edge detection technique;
generating a stereo logo comprising stereo spatially interleaved logo pictures including a representation of the logo, the stereo spatially interleaved logo pictures arranged in said detected spatially interleaved format; and
combining the stereo logo and the video image to generate the overlaid image in the detected spatially interleaved format.

2. The method of claim 1 comprising:
auto-detecting the spatially interleaved format by detecting at least one seam in said video image.

3. The method of claim 2 , wherein the at least one seam includes a horizontal seam and wherein said spatially interleaved format includes one of a top-bottom format, an interlaced format, and a checkerboard format.

4. The method of claim 2 , wherein the at least one seam includes a vertical seam and wherein said spatially interleaved format includes one of a side-by-side format, an interlaced format, and a checkerboard format.

5. The method of claim 1 , wherein said analysis is done using a view correlation technique and said generating the stereo logo further comprises:
down-sampling said logo to produce each of the stereo spatially interleaved pictures, said down-sampling being based on the spatially interleaved format.

6. The method of claim 5 , wherein said down-sampling is a horizontal down-sampling and wherein said spatially interleaved format includes one of a side-by-side format, an interlaced format, and a checkerboard format.

7. The method of claim 5 , wherein said down-sampling is a vertical down-sampling and wherein said spatially interleaved format includes one of a top-bottom format, an interlaced format, and a checkerboard format.

8. The method of claim 1 , wherein said generating the stereo logo further comprises:
positioning said logo at an identical location in each of the stereo spatially interleaved pictures.

9. The method of claim 1 , wherein said generating the stereo logo further comprises:
positioning said logo in a different location in each of the stereo spatially interleaved pictures.

10. The method of claim 1 , wherein said detecting further comprises:
identifying said spatially interleaved format for said video image.

11. A machine-readable medium having one or more executable instructions stored thereon, which when executed by a digital processing system causes the digital processing system to perform a method for inserting a logo into a video image to generate an overlaid image, the method comprising:
detecting presence of stereo spatially interleaved pictures in the video image, the stereo spatially interleaved pictures for the video image being arranged in a spatially interleaved format;
auto-detecting the interleaved format by analyzing a plurality of selective characteristics in said images and determining if said characteristics exceed a threshold that identifies them as stereo images, wherein said analysis is done using an edge detection technique;
generating a stereo logo comprising stereo spatially interleaved logo pictures including a representation of the logo, the stereo spatially interleaved logo pictures arranged in said detected spatially interleaved format; and
combining the stereo logo and the video image to generate the overlaid image in the detected spatially interleaved format.
