Abstract : Army PM JCALS, under the direction of the CALS Test Network Office (CINO), has developed Computer-assisted Data Acceptance (CADA) procedures for automating the acceptance of CALS raster, Type I, data The objective of these procedures is to reduce the labor requirements of the currently used manual quality assurance (QA) procedures. Effective implementation of the CADA procedures depends on the use of reliable image quality analysis and identification recognition techniques and tools. This report presents the results of testing these techniques and tools on a large base of CALS digital data. The tests were conducted at the Army CTN test bed, within the CALS Technology Center (CTC) of Army PM JCALS, Fort Monmouth, NJ. The initial step in this test effort was to develop suites of test data for both image and identification recognition techniques testing. For image quality testing, two different suites of test data were used. One suite (Image Data Set 1) represented the format and quality of CALS contractor procured data. The second set (Image Data Set 2) consisted of a representative subset from some 5,000 engineering drawings obtained from the Army and Air Force DSREDS and EDCARS repository sites. For identification recognition, three different sets of test data were used. ID Data Set 1 was sent to the selected neural network vendors to test their products at their sites. ID Data Set 2 was a larger and different set of DSREDS-DCARS test data that was used to test the vendors' recognition engines independently at the Army CTN test bed. ID Data Set 3 was developed to test the vendors' recognition algorithms on a suite of test data that closely represented good quality data expected to be procured from CALS contractors in the future.
