ABSTRACT
The word pattern may mean different things to different people. Speaking is to utter sound in prescribed patterns. Patterns are useful and practical. Humans are curious beings. One of the greatest joys of modern life is being able to find answers to questions instantly. Looking for a target string involves two steps: the people specify the string pattern to find. The computer searches for matches to the pattern in the document. Indeed computers are fast and efficient in matching textual patterns and are much faster than humans. Beware, there are security and privacy concerns when the people allow an app to collect their facial recognition information. Some say the future of transportation lies in self-driving cars. Its computer vision system must identify traffic signs and signals, vehicles, pedestrians, animals, and other objects that may be on or traveling the road.
