Abstract

To handle static text and logos in stabilized images without destabilizing the static text and logos, a method of handling overlay subpictures in stabilized images includes detecting an overlay subpicture in an input image, separating the overlay subpicture from the input image, stabilizing the input image to form a stabilized image, and merging the overlay subpicture with the stabilized image to obtain an output image.

Claims

1. A method of handling overlay subpictures in stabilized images comprising:

detecting an overlay subpicture in an input image;

stabilizing the input image to form a stabilized image; and

merging the overlay subpicture with the stabilized image to obtain an output image by;

processing a region the overlay subpicture is located in, and setting the overlay subpicture separated from the input image on the stabilized image;

wherein processing the region the overlay subpicture is located in comprises replacing the region the overlay subpicture is located in with image data from a second region of the stabilized image.

2. A method of handling overlay subpictures in stabilized images comprising:

detecting an overlay subpicture in an input image;

stabilizing the input image to form a stabilized image; and

merging the overlay subpicture with the stabilized image to obtain an output image by;

processing a region the overlay subpicture is located in, and setting the overlay subpicture separated from the input image on the stabilized image;

wherein processing the region the overlay subpicture is located in comprises replacing the region the overlay subpicture is located in with image data from a second region of at least one image of a plurality of images.

3. A method of handling overlay subpictures in stabilized images comprising:

detecting an overlay subpicture in an input image;

stabilizing the input image to form a stabilized image; and

merging the overlay subpicture with the stabilized image to obtain an output image by;

processing a region the overlay subpicture is located in, setting the overlay subpicture separated from the input image on the stabilized image, and smoothing a border region of the overlay subpicture and the stabilized image.

4. A method of handling overlay subpictures in stabilized images comprising:

detecting an overlay subpicture in an input image;

separating the overlay subpicture from the input image;

stabilizing the input image to form a stabilized image; and

merging the overlay subpicture with the stabilized image to obtain an output image;

wherein separating the overlay subpicture comprises;

recording a location of the overlay subpicture;

generating a copy of the overlay subpicture; and

removing the overlay subpicture from the input image.

5. The method of claim 4, wherein merging the overlay subpicture comprises:

laying the copy over the stabilized image at the location.
