I filtered some medical images in order to reduce the noise present in them and I'd like to plot the ROC curve to compare with other noise reduction methods. I have the original noisy images, the output filtered images and quality metrics values (PSNR, SSIM, SNR, MSE) of each filters.

Using the perfcurve (Statistics and Machine Learning Toolbox) function, create the ROC curve.

Please refer to this link for the documentation that contains how to plot the ROC curve and the code for it :
