Classification: CPC G | IPC G

Claim 0:
1. A device for upscaling resolution based on a slice image, the device comprising:
a convolution operation unit implemented with a processor configured to convert a low-resolution input slice image into a high-resolution output slice image using a convolutional neural network,
wherein the convolutional neural network includes:
a cascading block configured to perform a convolution operation and a residual operation using a convolution filter having a predetermined size on an input feature map generated from the low-resolution input slice image to generate an output feature map; and
an upscaling block configured to upscale the output feature map to generate the high-resolution output slice image,
wherein the upscaling block is configured to:
perform a first convolution operation using a first-type convolution filter and a shuffle operation on the output feature map to upscale the output feature map by a factor of a predetermined multiple and,
wherein the first-type convolution filter has a size of a vertical receptive field being smaller than a size of a horizontal receptive field.
