Main image
The product cut out, on a plain background
First image
Good resolution, the product cut out (freigestellt), seen from the front
Why cut out
Galaxus gives every cut-out image the same background colour so it blends into the shop page
Selection
Galaxus has used AI to select and process images since early 2023
Method

How each rule is measured.

Background colour
The background colour is the median of a thin band along all four edges. A pure-white rule passes only when that band is RGB 255, 255, 255; near-white values such as 253 are reported with their exact colour.
Scene photos
Room and lifestyle photos have no plain background to measure against, so fill, edges and shadow are marked as not measured rather than guessed.
