Sargur N. Srihari, Ching-Huei Wang · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1987
A framework for determining special interest objects in images is presented in the context of determining destination address blocks on images of mail pieces such as letters, magazines, and parcels.. The .iinages range from those having a high degree of global spatial structiire (e.g. carefully prepared letter mail envelopes which conform to specifications) to those with no structure (e.g., magazines with randomly pasted address labels). A method of planning the use of a large numbers of specialized tools is given. The control is based on the blackboard model and utilizes a dependency graph, knowledge rules and a blackboard.
