Ceramic Tile Dataset: 3301 Segmented Tiles with Shape and Colour Metrics

Tiles were photographed on a calibrated board, located with ArUco fiducials for metric scale, and segmented with a YOLO detector followed by SAM2. Each tile carries its cropped binary mask, bounding box, capture timestamp, pixel-to-millimetre scaling factor, mean RGB colour, a quantised palette colour, and six shape descriptors: area in pixels and square millimetres, eccentricity, solidity, aspect ratio, compactness and circularity.

The dataset is the tile inventory used by the surface-mosaic packing method described in the related publication.
