Abstract: Provided is an image processing method including upscaling an input image to generate an upscaled image, obtaining a first feature map and a second feature map by inputting the upscaled image to a convolutional neural network and performing a convolution operation on the upscaled image with one or more kernels included in the convolutional neural network, obtaining a gain map by inputting the first feature map to a first convolutional layer, obtaining an offset map by inputting the second feature map to a second convolutional layer, and generating an output image, based on the upscaled image, the gain map, and the offset map, wherein the convolutional neural network is configured to be trained to reduce a difference between a hue of the input image and a hue of the output image.

Abstract: An image processing device configured to obtain difference maps between a first frame or a first feature map corresponding to the first frame, and second feature maps corresponding to a second frame, obtain third feature maps and fourth feature maps by performing pooling processes on the difference maps according to a first size and a second size, obtain modified difference maps by weighted-summing the third feature maps and the fourth feature maps, identify any one collocated sample based on sizes of sample values of collocated samples of the modified difference maps corresponding to a current sample of the first frame, and determine a filter kernel used to obtain the second feature map corresponding to the modified difference map including the identified collocated sample, as a motion vector of the current sample.
