# TransBlobsToWorld

Applies a coordinate transform to a Blobs structure. The function computes the offset, orientation, and area of the blob with respect to the specified real-world coordinate system.

Note: The output of any vision tool that reports in real-world coordinates cannot be used as a fixture or region input to another vision tool.
