## :open_book: Introduction

This is a comprehensive image quality assessment (IQA) toolbox built with **pure Python and PyTorch**. We provide reimplementation of many mainstream full reference (FR) and no reference (NR) metrics (results are calibrated with official matlab scripts if exist). **With GPU acceleration, most of our implementations are much faster than Matlab.** Please refer to the following documents for details:

### :triangular_flag_on_post: Updates/Changelog

- ⏳**Sep, 2024**. Add [efficiency benchmark](tests/Efficiency_benchmark.csv). With $1080\times800$ image as inputs, all metrics complete **in under 1 second on the GPU** (NVIDIA V100), and most of them, except for `qalign` and `qalign_8bit`, require **less than 6GB of GPU memory**.

- ⚡**Aug, 2024**. Add `qalign_4bit` and `qalign_8bit` with much less memory requirement and similar performance.

- ✨**Aug, 2024**. Add `piqe` metric, and `niqe_matlab, brisque_matlab` with default matlab parameters (results have been calibrated with MATLAB R2021b).

- 💥**Aug, 2024**. Add `lpips+` and `lpips-vgg+` proposed in our paper [TOPIQ](https://arxiv.org/abs/2308.03060). 

- 🔥**June, 2024**. Add `arniqa` and its variances trained on different datasets, refer to official repo [here](https://github.com/miccunifi/ARNIQA). Thanks for the contribution from [Lorenzo Agnolucci](https://github.com/LorenzoAgnolucci) 🤗.

- **Apr 24, 2024**. Add `inception_score` and console entry point with `pyiqa` command.

- **Mar 11, 2024**. Add `unique`, refer to official repo [here](https://github.com/zwx8981/UNIQUE). Thanks for the contribution from [Weixia Zhang](https://github.com/zwx8981) 🤗.

## :zap: Quick Start

### Installation

```bash

# Install with pip

pip install pyiqa

# Install latest github version

pip uninstall pyiqa # if have older version installed already 

pip install git+https://github.com/chaofengc/IQA-PyTorch.git

# Install with git clone

git clone https://github.com/chaofengc/IQA-PyTorch.git

cd IQA-PyTorch

pip install -r requirements.txt

python setup.py develop

```

### Basic Usage 

You can simply use the package with commandline interface. 

```bash

# list all available metrics

pyiqa -ls

# test with default settings

pyiqa [metric_name(s)] --target [image_path or dir] --ref [image_path or dir]

```

### Advanced Usage with Codes

#### Test metrics 

```python

import pyiqa

import torch

# list all available metrics

print(pyiqa.list_models())

device = torch.device("cuda") if torch.cuda.is_available() else torch.device("cpu")

# create metric with default setting

iqa_metric = pyiqa.create_metric('lpips', device=device)

# check if lower better or higher better

print(iqa_metric.lower_better)

# example for iqa score inference

# Tensor inputs, img_tensor_x/y: (N, 3, H, W), RGB, 0 ~ 1

score_fr = iqa_metric(img_tensor_x, img_tensor_y)

# img path as inputs.

score_fr = iqa_metric('./ResultsCalibra/dist_dir/I03.bmp', './ResultsCalibra/ref_dir/I03.bmp')

# For FID metric, use directory or precomputed statistics as inputs

# refer to clean-fid for more details: https://github.com/GaParmar/clean-fid

fid_metric = pyiqa.create_metric('fid')

score = fid_metric('./ResultsCalibra/dist_dir/', './ResultsCalibra/ref_dir')

score = fid_metric('./ResultsCalibra/dist_dir/', dataset_name="FFHQ", dataset_res=1024, dataset_split="trainval70k")

```

#### Use as loss functions

Note that gradient propagation is disabled by default. Set `as_loss=True` to enable it as a loss function. **Not all metrics support backpropagation, please refer to [Model Cards](docs/ModelCard.md) and be sure that you are using it in a `lower_better` way.**

```python

lpips_loss = pyiqa.create_metric('lpips', device=device, as_loss=True)

ssim_loss = pyiqa.create_metric('ssimc', device=device, as_loss=True)

loss = 1 - ssim_loss(img_tensor_x, img_tensor_y)   # ssim is not lower better

```

#### Use custom settings and weights 

We also provide a flexible way to use custom settings and weights in case you want to retrain or fine-tune the models. 

```python

iqa_metric = pyiqa.create_metric('topiq_nr', device=device, **custom_opts)

# Note that if you train the model with this package, the weights will be saved in weight_dict['params']. Otherwise, please set weight_keys=None.

iqa_metric.load_weights('path/to/weights.pth', weight_keys='params')

```

#### Example Test script

Example test script with input directory/images and reference directory/images. 

```bash

# example for FR metric with dirs

python inference_iqa.py -m LPIPS[or lpips] -i ./ResultsCalibra/dist_dir[dist_img] -r ./ResultsCalibra/ref_dir[ref_img]

# example for NR metric with single image

python inference_iqa.py -m brisque -i ./ResultsCalibra/dist_dir/I03.bmp

```

### Results Calibration

Please refer to the [results calibration](./ResultsCalibra/ResultsCalibra.md) to verify the correctness of the python implementations compared with official scripts in matlab or python.

### ⏬ Download Benchmark Datasets

For convenience, we upload all related datasets to [huggingface IQA-Toolbox-Dataset](https://huggingface.co/datasets/chaofengc/IQA-Toolbox-Datasets), and corresponding meta information files to [huggingface IQA-Toolbox-Dataset-metainfo](https://huggingface.co/datasets/chaofengc/IQA-Toolbox-Datasets-metainfo). 

Here are example codes to download them from huggingface:

### Performance Evaluation Protocol

**We use official models for evaluation if available.** Otherwise, we use the following settings to train and evaluate different models for simplicity and consistency:

| Metric Type   | Train     | Test                                       | Results                                                  | 

| ------------- | --------- | ------------------------------------------ | -------------------------------------------------------- |

| FR            | KADID-10k | CSIQ, LIVE, TID2008, TID2013               | [FR benchmark results](tests/FR_benchmark_results.csv)   |

| NR            | KonIQ-10k | LIVEC, KonIQ-10k (official split), TID2013, SPAQ | [NR benchmark results](tests/NR_benchmark_results.csv)   |

| Aesthetic IQA | AVA       | AVA (official split)                       | [IAA benchmark results](tests/IAA_benchmark_results.csv) |

| Efficiency | CPU/GPU Time, GPU Memory | Average on $1080\times800$ image inputs | [Efficiency benchmark](tests/Efficiency_benchmark.csv) |

Results are calculated with:

- **PLCC without any correction**. Although test time value correction is common in IQA papers, we want to use the original value in our benchmark.

- **Full image single input.** We **do not** use multi-patch testing unless necessary.

Basically, we use the largest existing datasets for training, and cross dataset evaluation performance for fair comparison. The following models do not provide official weights, and are retrained by our scripts:

| Metric Type   | Reproduced Models |

| ------------- | ----------------------------- |

| FR            | `wadiqam_fr`  |

| NR            | `cnniqa`, `dbcnn`, `hyperiqa`,  `wadiqam_nr` |

| Aesthetic IQA | `nima`, `nima-vgg16-ava`      |

>[!NOTE]

>- Due to optimized training process, performance of some retrained approaches may be different with original paper.

>- Results of all **retrained models by ours** are normalized to [0, 1] and change to higher better for convenience.

>- Results of KonIQ-10k, AVA are both tested with official split.

>- NIMA is only applicable to AVA dataset now. We use `inception_resnet_v2` for default `nima`.

>- MUSIQ is not included in the IAA benchmark because we do not have train/split information of the official model.

### Benchmark Performance with Provided Script

Here is an example script to get performance benchmark on different datasets:

```bash

# NOTE: this script will test ALL specified metrics on ALL specified datasets

# Test default metrics on default datasets

python benchmark_results.py -m psnr ssim -d csiq tid2013 tid2008

# Test with your own options

python benchmark_results.py -m psnr --data_opt options/example_benchmark_data_opts.yml

python benchmark_results.py --metric_opt options/example_benchmark_metric_opts.yml tid2013 tid2008

python benchmark_results.py --metric_opt options/example_benchmark_metric_opts.yml --data_opt options/example_benchmark_data_opts.yml

```

## :hammer_and_wrench: Train

### Example Train Script

Example to train DBCNN on LIVEChallenge dataset

```bash

# train for single experiment

python pyiqa/train.py -opt options/train/DBCNN/train_DBCNN.yml

# train N splits for small datasets

python pyiqa/train_nsplits.py -opt options/train/DBCNN/train_DBCNN.yml

```

Example for distributed training
