Descriptive Representations of Remotely Sensed Image Data

Abstract : The paper deals with natural language descriptions of image data - words, phrases, or sentences which attempt to capture aspects of the content or 'meaning' of an image. Such an investigation has application to artificial intelligence, linguistic analysis, and retrieval. With respect to the topic of retrieval, the concept of an 'encyclopedic entry' for an image is considered, a representation complete enough to be used in place of the image to answer questions concerning the image. Topics such as canonical forms for descriptions, and methods of combining forms to obtain composite descriptions are discussed, using descriptions obtained from recent earth resources documents.
