Samsung patents image alignment using segmented masks

This patent describes a method for aligning two images by first breaking them into distinct sections called segmentation masks. It then calculates specific geometric adjustments, known as local homography matrices, for each matched section to create a single, aligned synthetic image.

Why it mattersThis technique could improve the accuracy of image stitching or background removal in photo editing software by handling different parts of an image individually rather than as one flat surface.

In the filing’s own words

An apparatus and method for processing an image are disclosed. The method includes: segmenting both a first image and a second image and generating segmentation mask pairs, each segmentation mask pair having a segmentation mask of the first image and a segmentation mask of the second image; generating local homography matrices of the first image with respect to the second image, based on the segmentation mask pairs, the first image, and the second image; and generating a synthetic image obtained by aligning the first image with the second image, wherein the aligning is performed based on the local homography matrices, the segmentation mask pairs, the first image, and the second image.

What exactly they claim (claim 1)

1. A method of processing an image, the method comprising: segmenting both a first image and a second image to generate first segmentation masks of the first image and second segmentation masks of th e second image, and generating segmentation mask pairs by deter 1 matches between t amentation masks and the second segmentation masks, each segmentation mask pair having a first segmentation mask of the first image and a second segmentation mask of the second image; generating local homography matrices of the first image with respect to the second image, based on the segmentation mask pairs, the first image, and the second image; and generating a synthetic image obtained by aligning the first image with the second image, wherein the aligning is performed based on the local homography matrices, the segmentation mask pairs, the first image, and the second image.
