Folowing up on the Tetraspective idea, in this experiment a different way of folding an image by interleaving its pixels is tested.
The source image in this case is the minimal and uniform Additive Squircles.
The border on each side of the source image is defined to take 25% of the image length. Then the border on each side of the image is folded inward.
As per Tetraspective, this transformation also results in an image that is one quarter of the original size and composed of four overlapping layers, which can be interleaved with each other to get the image back to its original size.
When looking closely at the image after interleaving of the four layers, it is possible to notice that adjacent pixels generally have very different colours, whereas looking at the image from a distance, blended colours can be perceived.
This is because the compound effect of four-pixel square cells in the folded/interleaved image reflects the uniformity of colours in the original image.
To make colours uniform even on a closer look - which can also be useful for image processing purposes - a further transformation is introduced in this experiment.
The colour of each pixel is recalculated as the weighted average of the colours of a 3x3 grid around that pixel (or 3x2 grid for a side pixel, or 2x2 grid for a corner pixel) and the weights are appropriately chosen to filter off variations within the four-pixel square cells.
The final image in this case has uniformly coloured areas and smooth colour transitions from one area to the next.
For a derived image see Phantometry.
