Classification: CPC G | IPC G

Claim 12:
13. A non-transitory computer-readable medium storing instructions, the instructions comprising: one or more instructions that, when executed by one or more processors, cause the one or more processors to:
extract one or more input patches based on an input image;
extract one or more pieces of feature information respectively corresponding to the one or more input patches, based on a dictionary including mapping information indicating mappings between a plurality of patches and pieces of feature information respectively corresponding to the plurality of patches; and
obtain a final image by performing a convolution operation between the extracted one or more pieces of feature information and a filter kernel,
wherein the dictionary is generated based on pieces of feature information output at an n−1-th convolution layer of a deep neural network (DNN) that includes n convolution layers and is trained to output a second image by performing image processing on a first image according to a preset purpose, and
the filter kernel is based on a filter kernel included in an n-th convolution layer of the DNN.
