Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 8:
9. A non-transitory computer-readable medium having a computer program stored thereon,
wherein the computer program, when executed on a computer, causes the computer to implement:
receiving a scanned image; and
processing the received image through an octave convolution-based neural network to output a high-quality image and an edge image for the received image,
wherein the octave convolution-based neural network comprises a plurality of octave encoder blocks and a plurality of octave decoder blocks,
wherein each octave encoder block comprises an octave convolutional layer, and is configured to output a high-frequency feature map and a low-frequency feature map for an image inputted to each octave encoder block, and
wherein a first octave encoder block, which is a first block among the plurality of octave encoder blocks, is configured to:
transfer the low-frequency feature map outputted from the first octave encoder block to a second octave encoder block, which is a second block among the plurality of octave encoder blocks, without transferring the high-frequency feature map outputted from the first octave encoder block to the second octave encoder block, and
transfer the high-frequency feature map outputted from the first octave encoder block to a first octave decoder block, which is the last block among the plurality of octave decoder blocks, without transferring the low-frequency feature map outputted from the first octave encoder block to the first octave decoder block.
