Challenges in document recognition bottom up and top down processes
Theodoros E Pavlidis · 1996
Human vision is guided by context but it has been difficult to replicate that process in machine vision. On the other hand bar codes have a precise formal definition so that high level structure (the equivalent) of context is used to guide low level recognition. The paper discusses some of the processes involved in bar code reading and uses them to suggest novel processes for mechanical text reading.
