US 12,217,435 B2 · Methods and systems for segmenting images

Abstract

The present disclosure is concerned with a computer implemented method for segmenting an image including a plurality of pixels. The method includes: processing the image to generate a first trimap and a second trimap, each trimap segmenting each pixel of the image into either a foreground region, a background region or an unknown region; performing a reconciliation algorithm on the first trimap and the second trimap to yield a merged trimap; processing the merged trimap and image to yield an alpha matte, the alpha matte including an alpha value for at least each pixel in the unknown region; and applying the alpha matte to the image to remove the background region therefrom.

Dependent claims

A method for processing an image comprising a plurality of pixels, the method comprising:

processing, by one or more computer devices, the image and generating a first trimap and a second trimap, each trimap segmenting each pixel of the image into either a foreground region, a background region or an unknown region;
generating a merged trimap by processing the first trimap and the second trimap according to a reconciliation algorithm;
processing, by the one or more computer devices, the merged trimap and image to yield an alpha matte, the alpha matte comprising an alpha value for at least each pixel in the unknown region;
generating a processed image by applying the alpha matte to the image to remove the background region therefrom;
and
outputting the processed image.

3 more elements

A system comprising:

one or more computer devices;
and
a non-transitory computer-readable storage medium storing instructions, which when executed by the one or more computer devices, cause the one or more computer devices to:
access an image comprising a plurality of pixels;
process the image and generate a first trimap and a second trimap, each trimap segmenting each pixel of the image into either a foreground region, a background region or an unknown region;
generate a merged trimap by processing the first trimap and the second trimap according to a reconciliation algorithm;
process the merged trimap and image to yield an alpha matte, the alpha matte comprising an alpha value for at least each pixel in the unknown region;
generate a processed image by applying the alpha matte to the image to remove the background region therefrom;
and
output the processed image.
