Image matting and alpha value techniques
First Claim
Patent Images
1. A method comprising:
- obtaining image data in a raw image format that is generated by one or more image sensors;
converting the obtained image data to describe a plurality of pixels, each said pixel associated with a respective one of a plurality of color channels; and
performing one or more matting operations on the converted image data.

Abstract
Image matting and alpha value techniques are described. In one or more implementations, techniques are described in which matting operations are applied to image data that is in a raw or substantially raw image format. This may be used to decompose image data into foreground and background images as well as to generate an alpha value that describes a linear combination of the foreground and background images for a respective pixel. Further, implementations are also described in which a plurality of alpha values is generated for each of a plurality of pixels. These alpha values may be utilized to support a variety of different functionality, such as matting operations and so on.

10. One or more non-transitory computer-readable storage media comprising instructions that are stored thereon that, responsive to execution by a computing device, causes the computing device to perform operations comprising:
-
obtaining image data in a raw image format that is generated by one or more image sensors, the image data obtained without performing non-linear post processing; and performing one or more operations on the obtained image data in the raw image format to decompose the image data into a foreground image, a background image, and one or more alpha values. - View Dependent Claims (11, 12)

13. A system comprising an image editing module, the image editing module configured to perform operations comprising:
-
obtaining image data comprising a single image generated by one or more sensors of an imaging device, the image data being obtained in a raw image format with minimal post processing; performing one or more matting operations on the obtained image data while still in the raw image format effective to decompose the obtained image data into a foreground image, a background image, and one or more alpha values. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
