EDSR (Enhanced Deep Super-Resolution) Single Image Super Resolution Matlab port.

■ Prerequisites ■

Matlab 2020b
Image Processing toolbox
Statistics and Machine Learning toolbox
Deep Learning Toolbox
Parallel Computing Toolbox

■ How to Test ■

Run EDSR_Test.m that calls EDSR_2xSuperResolution.m

Trained net is loaded on the line 5 of EDSR_2xSuperResolution.m

■ How to Perform EDSR Super-Resolution to your image file ■

Input image MyPicture.jpg should be pristine (not blurred) image. EDSR neural net will upscale the image by 2x.

img = imread("MyPicture.jpg"); % 1024x768 input image
imgSR = EDSR_2xSuperResolution(img);
imwrite(imgSR, "MyPicture_2xEDSR.png"); % 2048x1536 image is outputted

■ How to Train the network using DIV2K dataset ■

Download DIV2K dataset and place it on
DIV2K/DIV2K_train_HR for train data of 800 images
DIV2K/DIV2K_valid_HR for validation data of 100 images

Run CreateTrainingSetAll_DIV2K.m to create DIV2K_MatlabF folder that contains converted mat files.

■ How to Train the network using Flickr2K dataset ■

Run EDSR_Train_DIV2K.m to train and create EDSR_trained_2x_DIV2K.mat
rename it to EDSR_trained_2x.mat

Download Flickr2K dataset and place it on
Flickr2K/Flickr2K_HR for train data of 2650 images

Run CreateTrainingSetAll_Flickr2K.m to create Flickr2K_MatlabF folder that contains converted mat files.

Run EDSR_Train_Flickr2K.m to train and create EDSR_trained_2x_Flickr2K_epoch10.mat
rename it to EDSR_trained_2x.mat

■ Difference from original EDSR ■

1. Processes only Y component.
2. Mean squared error regression.
3. nResBlock==16, nFeatures==128, nResScale==0.05.
4. Only 2x super resolution is implemented.

■ Changelog ■

Version 20210228 1.0.2

・Updated EDSR_trained_2x.mat to Flickr2K dataset trained file to improve subjective SR quality.

Version 20210224 1.0.1

・Fix typo.

Version 20210223 1.0.0

・Initial release.

Hi, I did nothing but it seems the problem is gone now.

Ronald Rodriguez

I'd love to try out your program, but it's not possible to download it. Pressing the "Download" button results in a message that says, "We're sorry, but something went wrong. If you are the application owner check the logs for more information." I hope you can fix this soon.
