difference of SSIM and multissim?
9 views (last 30 days)
I work on MRI images and now I assess different k-space trajectories on mri images.
I used ssim and nrmse to assess the quality of images. 1st off, I don't know what is the difference between ssim and multissim, as they give different values for one comparison?
2nd, as I increase k-space sampling density the ssim value starts to decrease from a point while I see the quality of image is high and it's similiar to main image.

The documentation describes the differences:
Without any quantification of "starts to decrease from a point" and "I see the quality of the image is high", all anyone can conclude is that the error is increasing, but you simply aren't noticing the increased error.
