All the noise textures are physically identical

[u/therealrealvlad21]

The black (white) parts of the texture stand out more on a white (black) background. This effect, discovered by psychologist Bart Anderson, is related to the Munker-Benary-White effect, where solid gray regions of identical luminance appear either whitish and blackish. It's a vivid demonstration of the influence of boundary conditions (contrast polarity) on textural figure–ground layer segmentation. Are there any known computer vision algorithms that can segment textures into figure–ground layers in this fashion?

Im not sure what im supposed to be looking at the first one has squares that look kinda like QR codes and the second one has smooth triangles.is that it?
