+# Julia SSIM trap
+
+[SSIM](https://en.wikipedia.org/wiki/Structural_similarity) is a metric used to compare image similarity.
+
+While original SSIM is computed against the luma channel (i.e. in a gray-scale),
+the Julia language [computes a weighted combination of per-channel SSIM's](https://github.com/JuliaImages/ImageQualityIndexes.jl/blob/e014cee9bef7023a1047b6eb0cbe49fbf28f2fed/src/ssim.jl#L39-L41).
+
+This sample is a white image and a gray image that are reported equal by Julia SSIM.
+It also traps all the suggestions for color-weighted SSIM given here:

+# Original SSIM trap
+
+[SSIM](https://en.wikipedia.org/wiki/Structural_similarity) is a metric used to compare image similarity.
+
+The sample provides two different images. However, since the original SSIM implementation
+[converts images into
+gray-scale](https://github.com/obartra/ssim/blob/ca8e3c6a6ff5f4f2e232239e0c3d91806f3c97d5/src/index.ts#L104),
+SSIM metric will yield a perfect match for these images.
