A digital ink system can identify a reference time from which to represent a current time. The system can generate an absolute age of each ink point of the ink stroke based on the reference time.

In some cases, the rhythm can be the same rhythm as when the ink stroke was originally drawn. In other cases, the rhythm can be modified based on the rhythm the ink stroke was originally drawn. For example, the original rhythm may be accelerating, decelerating, skewed, compressed, affine, or non-affine.

In one aspect, a processor selects a street level image that is likely to be near an address of interest. The processor identifies those portions of the image that are visually similar to street numbers, and then extracts the numeric values of the characters displayed in such portions.

The human operator confirms, by looking at the image portion, whether the image portion appears to be a building number that matches the extracted value. If so, the processor stores a value that associates that building number with the street level image.
