CDD-11

CDD-11 is a compound-degradation image restoration dataset with 11 degradation types. Each sample shares the same filename across all folders (paired by 000001.png, 000002.png, …).

Repository branches

Branch Contents
main Training and test datasets only
methods Restored images from other methods only (no metrics, logs, or other files)

Download

Datasets (main branch):

git clone https://huggingface.co/datasets/gy65896/CDD-11
cd CDD-11
unzip train.zip && unzip test.zip

Method results (methods branch):

git clone -b methods https://huggingface.co/datasets/gy65896/CDD-11 CDD-11-methods

Dataset layout (main branch)

After unpacking train.zip and test.zip:

.
|-- train/
|   |-- clear/          # clean GT
|   |   |-- 000001.png
|   |   |-- 000002.png
|   |-- low/
|   |-- haze/
|   |-- rain/
|   |-- snow/
|   |-- low_haze/
|   |-- low_rain/
|   |-- low_snow/
|   |-- haze_rain/

    |-- low_snow/
    |-- haze_rain/
    |-- haze_snow/
    |-- low_haze_rain/
    |-- low_haze_snow/

clear/ holds the ground-truth images; the other folders contain the corresponding degraded versions with matching filenames.

Methods layout (methods branch)

The methods branch stores restored images only—no metrics, configs, or other artifacts.

.
|-- <MethodName>/
|   |-- low/
|   |   |-- 00002.png
|   |-- haze/
|   |-- rain/
|   |-- ...

Each method directory mirrors the test-set degradation folders; filenames match test/clear/ on main for comparison.
