Abstract
A method includes obtaining multiple images via a multi-frame capture operation. The method also includes processing the multiple images using a multi-frame processing pipeline to generate a single frame image. The method also includes processing the multiple images to generate a backlit segmentation map that identifies regions in a scene of the single frame image that are illuminated by at least one background light source. The method also includes generating a dehazed single frame image based on modifying a local contrast of the single frame image using the backlit segmentation map.
Claims20
A method comprising:
- obtaining multiple images via a multi-frame capture operation;
- processing the multiple images using a multi-frame processing pipeline to generate a single frame image;
- processing the multiple images to generate a backlit segmentation map that identifies regions in a scene of the single frame image that are illuminated by at least one background light source;
- and
- generating a dehazed single frame image based on modifying a local contrast of the single frame image using the backlit segmentation map.
An electronic device comprising:
- at least one processing device configured to:
- obtain multiple images via a multi-frame capture operation;
- process the multiple images using a multi-frame processing pipeline to generate a single frame image;
- process the multiple images to generate a backlit segmentation map that identifies regions in a scene of the single frame image that are illuminated by at least one background light source;
- and
- generate a dehazed single frame image based on modifying a local contrast of the single frame image using the backlit segmentation map.
A non-transitory machine readable medium comprising instructions that when executed cause at least one processor of an electronic device to:
- obtain multiple images via a multi-frame capture operation;
- process the multiple images using a multi-frame processing pipeline to generate a single frame image;
- process the multiple images to generate a backlit segmentation map that identifies regions in a scene of the single frame image that are illuminated by at least one background light source;
- and
- generate a dehazed single frame image based on modifying a local contrast of the single frame image using the backlit segmentation map.
