Atlas demonstration: the free source photo and the computed Quickshift Superpixels. A complex composition of statues and fabric appears fragmented into muted earthy tones. The algorithm has grouped subtle tonal variations into jagged, white-outlined cells that perfectly illustrate the segmentation process.

Prompt

Apply a Quickshift Superpixels effect, dividing the photograph into many irregular, tightly adjoining patches that follow local color boundaries. Fill each patch with its average source color, creating an uneven mosaic with crisp borders and simplified texture rather than geometric tiles. Keep the original subject and composition.

Identify

The photo is divided into irregular regions called superpixels1, which often follow color boundaries rather than recognizable objects.

Principle

Quickshift estimates density2 using pixel color and position, then links each pixel to its nearest neighbor with higher density. Cutting links beyond a distance limit separates the pixels into regions.

Try it out

Vary the distance limit and watch small regions merge or separate.

Classification

Calculated image processing result.
