Need help regarding Image collection for comparison and plotting graph.

Suppose I want to compare our processed image with the processed image of previous research paper in terms of PSNR value and plot a graph for comparison among them. How to do that ? From where i can get the output images of past research article. What is the process for doing the comparison? Please help me.

For PSNR you have inbuilt function. You can also have a look on other factor for comparison, it is known as structural similiraity index, read about ssim. Coming about images, if author menitions dataset, he shall give a link to the dataset. If not given you can try to mail the author and ask for data. Overall it depends on what specific problem you are talking about.

IPT has ssim() as of R2014a

To graph, use plot()
