single-image-super-resolution-1032

Use Case and High-Level Description

An Attention-Based Approach for Single Image Super Resolution but with reduced number of channels and changes in network architecture. It enhances the resolution of the input image by a factor of 4.

Example

Low resolution:

_images/street_480x270.png

Bicubic interpolation:

_images/x4c_street_480x270.png

Super resolution:

_images/x4_street_480x270.png

Specification

Metric

Value

PSNR

29.29 dB

GFlops

11.654

MParams

0.030

Source framework

PyTorch*

For reference, PSNR for bicubic upsampling on test dataset is 26.79 dB.

Inputs

  1. Image, name: 0, shape: 1, 3, 270, 480 in the format B, C, H, W, where:

    • B - batch size

    • C - number of channels

    • H - image height

    • W - image width

  2. Bicubic interpolation of the input image, name: 1, shape: 1, 3, 1080, 1920 in the format B, C, H, W, where:

    • B - batch size

    • C - number of channels

    • H - image height

    • W - image width

    Expected color order is BGR.

Outputs

The net output is a blob with shapes 1, 3, 1080, 1920 that contains image after super resolution.
