Antighosting method using binocular suppression

1. A method of processing a source left view and a source right view of a 3D image comprising:

identifying at least one ghosted region or ghosting region in an original left view and/or in an original right view in a linear space;

processing said at least one identified ghosted region or ghosting region by performing a blurring of said at least one identified ghosted region or ghosting region in order to create a binocular suppression effect for said at least one identified ghosted region or ghosting region then providing a new 3D image in a display space formed by the processed left and/or right views in said linear space, said blurring comprising removing high spatial frequencies in said at least one identified ghosted region or ghosting regions, and wherein the processing further comprises a singularity processing that takes into account a user's dominant eye.

2. The method of processing according to claim 1 , wherein identifying at least one ghosted region or one ghosting region is performed using a ghost simulation.

3. The method of processing according to claim 1 , wherein processing said at least one identified ghosted region or ghosting region comprises changing a contrast in order to generate binocular suppression in said at least one identified ghosted region or ghosting region.

4. The method of processing according to claim 1 , wherein processing said at least one identified ghosted region or ghosting region comprises modifying color of said at least one identified ghosted region or ghosting region by de saturating color of said at least one identified ghosted region or ghosting region.

5. The method of processing according to claim 1 , wherein the blurring of said at least one identified ghosted region or ghosting region comprises:

calculating a left and/or a right alpha masks wherein a parameter alpha of those masks is determined, in a range of values comprised between 0 to 1, such that it is closer to 1 in said at least one identified ghosted region or ghosting region and closer to 0 out of said at least one identified ghosted region or ghosting region,

blending the original left view with a blurred left view with the alpha mask of the left view and/or blending the original right view with the blurred right view with the alpha mask of the right view, and

delivering an obtained blended left/right view being an addition of an alpha part of the blurred left/right view and a (1-alpha) part of the original left/right view.

6. The method of processing according to claim 5 , wherein said blurring further comprises modifying left and right alpha masks, in exchanging disparity information between the left and the right alpha masks taking account of the disparity map, such that a quality of image in the crosstalk generating region is decreased and a quality of image in the corresponding region is increased.

7. The method of processing according to claim 6 , wherein said blurring further comprises filtering left and/or right alpha masks belonging to a same object in the left and/or right view so that performing a double processing is avoided.

8. The method of processing according to claim 1 , wherein the method is applied on 3D content, at the post-production level.

9. The method of processing according to claim 1 , wherein the method is applied on 3D content of a set-top box or gateway embedded processing.
