摘要： A method and apparatus for image restoration based on burst images. The method includes generating a plurality of feature representations corresponding to individual images of a burst image set by encoding the individual images (810), determining a reference feature representation from among the plurality of feature representations (820), determining a first comparison pair including the reference feature representation and a first feature representation of the plurality of feature representations (830), generating a first motion-embedding feature representation of the first comparison pair based on a similarity score map of the reference feature representation and the first feature representation (840), generating a fusion result by fusing a plurality of motion-embedding feature representations including the first motion-embedding feature representation (850), and generating at least one restored image by decoding the fusion result (860).

摘要： Methods and apparatuses with training or image enhancement are disclosed. The image enhancement method includes obtaining an input image, estimating a noise distribution of the input image by implementing a noise model based on the input image, and generating an enhanced image by implementing an image enhancement model dependent on the input image and the estimated noise distribution.

摘要： A processor-implemented method includes: obtaining a plurality of image frames acquired for a scene within a predetermined time; determining loss values respectively corresponding to the plurality of image frames; determining a reference frame among the plurality of image frames based on the loss values; and generating a final image of the scene based on the reference frame.
