 | This quarter, we re-designed the Shape-DNA based rule line cleaning algorithm to minimize the degradation of the shape of text characters. Recall that in the Shape-DNA based cleaning approach, the projection onto the Shape-DNA space produces a rule line distance image that is used to clean the rule lines. However, this cleaning process can and does remove portions of legitimate text characters that resemble rule lines. Therefore, instead of using ... |

| The Navy system for accessing, training, assigning, developing, and maintaining Sailors' careers consists of numerous semi-autonomous organizations whose interdependence is well-known but not well understood. Each organization within the personnel management network maintains independent operational and archival information technology systems, measures success locally, and makes management decisions without the benefit of fully understanding the impacts that their decisions have on the extended enterprise. To overcome the inherent inefficiency of independently ... |
