The paper describes the results of a programme of research aimed at developing a mechanism for identifying and describing particular cloud patterns in weather satellite images. The ability to automatically track a defined cloud formation across a time sequence of images would be very useful in the prediction of wind speed and direction, and the ability to register the way in which a cloud formation evolves with time would support forecasts of future weather events. The application of such techniques is not limited to weather satellite images, however, but can also be used in other fields, such as medical imaging, where non-static images are also to be found.< >

Traffic observed by video cameras or captured on video tape can now be counted automatically in real-time. The aim of the TRIP ii system is to take full advantage of the area sensing capability of video images. It is different from many earlier systems since it is based upon an inexpensive IBM AT microcomputer and can processes complex pattern information by simulating the operation of a neural network. In this particular case the vehicle detection algorithm relies on the ability of the TRIP ii system to learn from example and discriminate between complex patterns within video images of traffic scenes.< >

The authors present their conception of a vision system and how they are structuring knowledge about imageprocessing to allow, to a certain extent, autonomy of the system for manipulation of processing sequences. Use is made of artificial intelligence techniques for knowledge representation to design a frame system which takes into account both conceptual processings and programs.

This paper describes an imageprocessing system resulting from a collaborative research project involving Lancashire Polytechnic, the Royal Aircraft Establishment, Farnborough, and C. W. Controls Ltd. , Southport. The main aim of the project was to develop a low cost microprocessor-based imageprocessing system to promote and develop the use of satellite image data for remotesensing applications, particularly for users located in universities, polytechnics and colleges.

On accumule de plus en plus de données sous forme d'images, surtout dans les domaines où interviennent la microscopie ou la télédétection. ii n'est done pas surprenant que les statisticiens s'intéressent au développement de techniques permettant d'analyser les données hyper-structurées que nous procurent ces images. Nous voulons brosser ici un tableau des progrès accomplis dans ce domaine en nous attardant plus particulièrement à deux de leurs applications. La première concerne la classification de parcelles de terre en fonction de l'utilisation des sols à partir d'une composition photographique réalisée par satellite. La seconde application à trait a la micrographie des électrons. [ABSTRACT FROM AUTHOR]

A remotesensing workshop, sponsored by the National Science Foundation and Purdue University, was held at Purdue on February 28 through March 1, 1984. Briefly stated, the purpose of the workshop was to define the directions which engineering-oriented research in remotesensing should be taking in order to maximize its scientific and technological returns. This paper presents an overview of the results of that workshop.

Digital terrain models (DTM) have been successfully applied to many problems in remotesensing. In this paper, three examples are presented. The author first corrects shading artifacts caused by varying solar illumination conditions and different viewing angles in remotely sensed images. An image with the artifacts corrected shows useful information that is not apparent in the original image. The author next presents a three-dimensional perspective view of a terrain with a corresponding aerial photograph mapped on it, which, incidentally greatly helps image interpretation. Finally the author reports here on the first attempt anywhere to register ordinary 35-mm color slide images with digital geographic terrain data and to generate a distance image for visibility study. And as an application of this distance information, the author shows a simulated fog as a function of distance.

A new type of range sensing method which is based on the principle of triangulation has been developed. A mirror tunnel is placed between an observation lens and an object to be measured;a light beam is projected through the observation lens on to the object;the projected light spot is imaged by the observation lens on the image plane after reflection with the mirror;a position of the light spot on the object can be determined according to the triangulation. The width of an optical system can be reduced to remarkably smaller than the effective base line of the triangulation, and it may be suitable to miniaturize the size of range sensor such as a proximity sensor.
