# DF2K_BHI SISR Dataset |
|
|
|
This is a filtered version of the DF2K dataset, specifically aimed for single image super-resolution model training. |
|
It is a result, or is one of the testing sets, for [my huggingface community blog post on my BHI-Filtering method](https://huggingface.co/blog/Phips/bhi-filtering). |
|
|
|
## Dataset Details |
|
|
|
This is based on the DF2K dataset, which consists of 3450 images. |
|
|
|
These images then have been tiled into 21'387 512x512px tiles for faster sisr I/O training speed. |
|
|
|
The BHI filtering has been applied with the following default threshold values: |
|
|
|
Blockiness < 30 |
|
HyperIQA >= 0.2 |
|
IC9600 >= 0.4 |
|
|
|
Which results in this DF2K_BHI dataset with 12'639 512x512 training tiles. |
|
|
|
## Visualization |
|
|
|
Here is a visual example of the first few tiles that are in the dataset: |

## Training |
|
|
|
As can be seen in the following training validation tensorboard graphs (DIV2K validation dataset), this BHI-filtered version of the DF2K dataset is able to achieve higher or similiar metric scores while seeing a reduction of -40.9% in training tiles quantity. |
|
|
|
Here is the training validation metrics on the DIV2K validation dataset, using the plksr_tiny architecture option, in comparison to the tiled full DF2K dataset: |
|
|
|
Tiled DF2K dataset (here called X): 21'387 tiles |
|
DF2K_BHI dataset: 12'639 tiles |
