Image processing
Since the use of intensity as a feature for classification is frequently unsatisfactory in these monochromatic images, the importance of features based on texture is considered.
Abstract
Ultrasonic recordings and radiographs contain in pictorial form information required for decision making. Many investigators are actively engaged in the interpretation of images, obtained by both aeroplanes and satellites, by automated techniques. The techniques employed to process these images are relevant to the needs of engineering and medical diagnosis from both ultrasonic and radiographic images. In particular, since the use of intensity as a feature for classification is frequently unsatisfactory in these monochromatic images, the importance of features based on texture is considered. In addition the development of automated processing of ultrasonic records of British Rail track is discussed.
