Well, they are both done in a grid, using squares that are (ideally) uniform in size and shape. The same limitations apply to both.

A quick check says it doesn't meet the definition, but they seem pretty similar to me. They are conceptually similar and I think the automated embroidering machines, those that turn pictures into patterns and then stitch them, work on that principle.

I could maybe ask the lady at the Grange Hall. She has one of those machines. Err... Don't tell her, but the output is uninspiring.
