Abstract
In one implementation, a method includes obtaining an image. The method includes generating a plurality of denoised images by denoising the image using a respective plurality of denoisers, wherein the plurality of denoisers includes a first denoiser associated with a first level of exposure and a second denoiser associated with a second level of exposure. The method includes generating a combined image by combining the plurality of denoised images.
Claims18
A method comprising:
- obtaining an image;
- generating a plurality of denoised images by denoising the image using a respective plurality of denoisers, wherein the plurality of denoisers includes a first denoiser that applies a first denoising algorithm associated with a first level of exposure and a first level of noise, a second denoiser that applies a second denoising algorithm associated with a second level of exposure, and a third denoiser that applies a third denoising algorithm associated with the first level of exposure and a second level of noise;
- and
- generating a combined image by combining the plurality of denoised images.
An electronic device comprising:
- a non-transitory memory;
- and
- one or more processors configured to:
- obtain an image;
- generate a plurality of denoised images by denoising the image using a respective plurality of denoisers, wherein the plurality of denoisers includes a first denoiser that applies a first denoising algorithm associated with a first level of exposure and a first level of noise, a second denoiser that applies a second denoising algorithm associated with a second level of exposure, and a third denoiser that applies a third denoising algorithm associated with the first level of exposure and a second level of noise;
- and
- generate a combined image by combining the plurality of denoised images.
A non-transitory computer-readable medium having instructions encoded thereon that, when executed by one or more processors of an electronic device, causes the electronic device to perform a method comprising:
- obtaining an image;
- generating a plurality of denoised images by denoising the image using a respective plurality of denoisers, wherein the plurality of denoisers includes a first denoiser that applies a first denoising algorithm associated with a first level of exposure and a first level of noise, a second denoiser that applies a second denoising algorithm associated with a second level of exposure, and a third denoiser that applies a third denoising algorithm associated with the first level of exposure and a second level of noise;
- and
- generating a combined image by combining the plurality of denoised images.
