Litho Scanning Techniques.
Abstract
This effort continued to investigate raster processing techniques, referred to as the Automatic Feature Tracking algorithm, demonstrated to be feasible under previous contract to RADC (F30602-78-C-0313). The current effort considered methods of optimizing the algorithm, determined optimal parameters to track various features, and examined alternate templates for the various features. The goal of this contract was to reduce the processing requirements, and hence the processing time, while preserving the quality of the feature tracking results. In addition to performing the feature tracking, various timing simulations were conducted to demonstrate the processing speed that could be achieved using the existing algorithm and off-the-shelf hardware. The tracking of a symbolized railroad feature could be performed at a rate of approximately ten (10) inches per minute if a computer configuration had the appropriate hardware peripherals. The DeAnza IP-5500 Image Display System and the Floating Point Systems AP-120BF are the devices that could achieve that tracking rate. Alternate hardware was examined with possible changes in the template matching algorithm and the template design to further accelerate processing speed of the feature tracking algorithm. (Author)
