Save SSIM index output
3 views (last 30 days)
I have 2 images (A,B) that i want to compare using the SSIM Index. I am using the command
[ssimval, ssimmap] = ssim(A,B);
When i plot ssimmap i can see the different structures. When i save the ssimmap and then read the image:
When i plot 'NewImage' it looks all flat, it is different than 'ssimmap'. Is there something different about 'ssimmap' that it has to be saved in a special way? I want to be able to save ssimmap as an output file.
