Abstract
Seamless image compositions may be created. A plurality of images may be received, one image being a base image and the remaining image or images being source images. A selection may be received of one or more regions of one or more of the sources images to be copied onto the base image. An input may be received setting a blend parameter for each of the selected regions. The plurality of images may be blended together into a composite image by matching image gradients across one or more seams of the composite image. The image gradients may be based on the blend parameters. In one embodiment, input may be received to set a modified blend parameter for at least one of the selected regions and the plurality of images may be re-blended into a composite image in a similar manner but using the modified blend parameter.

A method, comprising:
- receiving a plurality of images;
- receiving an indication of one of the plurality of images as a base image, wherein the remaining not indicated images comprise one or more source images;
- receiving a selection of one or more regions of the one or more source images to be copied onto the base image;
- receiving input setting a blend parameter for each of the selected regions, wherein the blend parameter for each selected region includes a blend amount for the selected region;
- and
- blending the plurality of images together into a composite image, wherein said blending comprises matching image gradients across one or more seams of the composite image, wherein the image gradients are based on the blend parameters,
- wherein said blending further comprises:
- storing image data in a buffer for each of the plurality of images;
- storing a blend map for each of the selected regions based on each selected region's corresponding blend parameter;
