An active contour model, Snake, was developed as a useful segmenting and tracking tool for rigid or non-rigid (i.e. deformable) objects by Kass in 1987.
Finally, the timing of decision-making about second children has not been studied in this population, and we did not want to artificially eliminate a potentially useful segment from our study by setting too stringent a time limit since the birth of the first child.
Clearly for the healthy patients this results in a minimal number of useful segments such that there were fewer than 10, in this case the deficiencies in each individual were supplemented by random extra segments from other patient groups.
The ADHD group had an average of 38 useful segments (sd = 13.6) in the eyes-closed condition and 43 segments (sd = 12.7) during eyes-open, whereas the control group had an average of 43 segments (sd = 14.2) in the eyes-closed condition and 46 segments (sd = 9.5) during eyes-open.
What Pujols does have is hours and hours of visually recorded memory, and the ability to "chunk" that information into useful segments.
Actual useful segments of orbits are likely to be somewhat longer, but should not be shorter than the times listed here.

This changed with industrialization and the growth of cities, when age became a useful means of segmenting the population.
Language is a useful criterion for segmenting advertising markets, and advertisers should be able to include this in schemes to customize their own advertising plans without wasting network or processing resources.
En bloc resection of the diseased segment is a useful surgical technique in the treatment of benign and malignant bone lesions.
One would expect epoxy groups to line up circumferentially in a nanotube, leading to its transverse fracture into shorter segments, in a useful cutting process.
