DIFFERENCE DETECTION

The "blink" principle was first used for the detection of changes in position and luminousity of stars and its is being used now in proofreading of documents by employing an instrument called a Hinman Collator. An instrument using this principle together with a television viewing system offers good potential for difference detection in imagery and photography. Tests were carried out using an instrument of this type and a Hinman Collator. Particularly good results were obtained with ERTS imagery. As a result of the tests, the features of an instrument for difference detection in imagery and photography are outlined. /Author/
