Your sigma here is 0.5, and assuming 3 x 3 is symmetrical around the centre, that would mean it truncates at 3/2 = 1.5 = 3 sigma. So you could use gaussian_filter (img, 0.5, order=0, truncate=3.0) and see if you get the same result as ...

WebNov 12, 2024 · Hi. I’m trying to implement the MEFSSIM metric proposed in 《Perceptual Quality Assessment for Multi-Exposure Image Fusion》. However, I find it hard to implement it in an efficient and highly-vectorized way. Does anyone have a better solution? (There are several pytorch implementations of mefssim available on github, but they are all … Webexample. ssimval = ssim (A,ref) calculates the structural similarity (SSIM) index for grayscale image or volume A using ref as the reference image or volume. A value closer to 1 indicates better image quality. ssimval = ssim (A,ref,Name,Value) calculates the SSIM, using name-value pairs to control aspects of the computation.
