You can check documentation [here](http://sewar.readthedocs.io/).\n\n\n## Implemented metrics\n- [x] Mean Squared Error (MSE) \n- [x] Root Mean Squared Error (RMSE)\n- [x] Peak Signal-to-Noise Ratio (PSNR) [[1]](https://ieeexplore.ieee.org/abstract/document/1284395/)\n- [x] Structural Similarity Index (SSIM) [[1]](https://ieeexplore.ieee.org/abstract/document/1284395/)\n- [x] Universal Quality Image Index (UQI) [[2]](https://ieeexplore.ieee.org/document/995823/)\n- [x] Multi-scale Structural Similarity Index (MS-SSIM) [[3]](https://ieeexplore.ieee.org/abstract/document/1292216/)\n- [x] Erreur Relative Globale Adimensionnelle de Synthèse (ERGAS) [[4]](https://hal.archives-ouvertes.fr/hal-00395027/)\n- [x] Spatial Correlation Coefficient (SCC) [[5]](https://www.tandfonline.com/doi/abs/10.1080/014311698215973)\n- [x] Relative Average Spectral Error (RASE) [[6]](https://ieeexplore.ieee.org/document/1304896/)\n- [x] Spectral Angle Mapper (SAM) [[7]](https://ntrs.nasa.gov/search.jsp?R=19940012238)\n- [x] Spectral Distortion Index (D_lambda) [[8]](https://www.ingentaconnect.com/content/asprs/pers/2008/00000074/00000002/art00003)\n- [x] Spatial Distortion Index (D_S) [[8]](https://www.ingentaconnect.com/content/asprs/pers/2008/00000074/00000002/art00003)\n- [x] Quality with No Reference (QNR) [[8]](https://www.ingentaconnect.com/content/asprs/pers/2008/00000074/00000002/art00003)\n- [x] Visual Information Fidelity (VIF) [[9]](https://ieeexplore.ieee.org/abstract/document/1576816/)\n- [x] Block Sensitive - Peak Signal-to-Noise Ratio (PSNR-B) [[10]](https://ieeexplore.ieee.org/abstract/document/5535179/)\n\n## Todo\n- [ ] Add command-line support for No-reference metrics\n\n## Installation\nJust as simple as\n```\npip install sewar\n```\n## Example usage\na simple example to use UQI\n```python\n>>> from sewar.full_ref import uqi\n>>> uqi(img1,img2)\n0.9586952304831419\n```\n\n## Example usage for command line interface\n```\nsewar [metric] [GT path] [P path] (any extra parameters)\n```\nAn example to use SSIM\n```shell\nfoo@bar:~$ sewar ssim images/ground_truth.tif images/deformed.tif -ws 13\nssim : 0.8947009811410856\n```\nAvailable metrics list\n```\nmse, rmse, psnr, rmse_sw, uqi, ssim, ergas, scc, rase, sam, msssim, vifp, psnrb \n```\n\n## Contributors\nSpecial thanks to @sachinpuranik99 and @sunwj.\n\n## References\n[1] \"Image quality assessment: from error visibility to structural similarity.\" 2004)
