Abstract: The present disclosure provides methods, apparatuses, systems, and computer-readable mediums for demosaicing images by an apparatus. A method includes obtaining, from a plurality of sensors of the apparatus, a plurality of mosaic images, concatenating each image of the plurality of mosaic images with encoded embeddings of the corresponding mosaic pattern of the sensor of the plurality of sensors that captured that image of the plurality of mosaic images, providing the concatenated plurality of mosaic images to a machine learning model, and acquiring, from the machine learning model, a plurality of demosaiced images corresponding to the plurality of mosaic images. Each sensor of the plurality of sensors has a corresponding mosaic pattern from among a plurality of mosaic patterns.

Abstract: A method includes collecting a first set of images of a scene with a sensor in accordance with a first condition; collecting a second set of images of the scene with the sensor in accordance with a second condition; collecting one or more noise sample sets based on the first set of images and the second set of images; generating a calibrated noise model based on the one or more noise sample sets; and generating a noisy image by applying the calibrated noise model to a noise free image.

Abstract: A method for processing image data may include: obtaining a raw input image that is captured under an input illumination; obtaining a target illumination from a user input; obtaining an intermediate image having colors captured under a reference illumination, from the raw input image, based on a first color transform that maps the input illumination to the reference illumination in an illumination dataset of raw sensor images that are captured under a plurality of different illuminations; and obtaining an output image having colors captured under the target illumination, from the intermediate image, based on a second color transform that maps the reference illumination in the illumination dataset to the target illumination.

Abstract: A method of generating a low-light image is provided. The method includes receiving a raw image, removing an amount of first illumination from the raw image, applying a low exposure condition to the raw image having the amount of first illumination removed, and applying an amount of low-light illumination to the raw image having the applied low exposure condition.
