Kandidats Image Processing System, Robert M. Haralick, Gary J. Minden, Dale R. Johnson, Amrendra Singh, William F. Bryant, Craig A. Paul

LARS Symposia

KANDIDATS is a comprehensive digital image processing system that interacts with the user at a command string level. It includes prompting for parameter input and checks user input for errors. Image analyses available in KANDIDATS consist of utility functions, image transform operations, spatial clustering, and Bayesian classification. The versatility and capabilities of KANDIDATS arise from a modular programming structure and file structure. These attributes allow processing of images that are a few thousand rows by a few thousand columns in a minicomputer system with only 32 K words of main memory.

Tree System Approach For Landsat Data Interpretation, R. Y. Li, K. S. Fu

LARS Symposia

This paper describes a tree system approach which interpretates highways and rivers from LANDSAT pictures. The basic definitions of tree grammars and tree automaton and a grammatical inference procedure are first introduced. The interpretation process is conceived as a process of continuous verification of the hypothesized descriptions of objects in the picture. The LANDSAT imagery map of Lafayette, Indiana is used as a training data set and tree grammar is inferred from the interpretation process. The versatility of this set of syntactic rules is tested on a different data set and the initial results are reported.

A Landsat Digital Image Rectification System, Peter Van Wie, Maurice Stein

LARS Symposia

DIRS is a Digital Image Rectification System for the geometric correction of Landsat Multispectral Scanner digital image data. DIRS removes spatial distortions from the data and brings it into conformance with the Universal Transverse Mercator (UTM) map projection. Scene data in the form of landmarks or Ground Control Points (GCPs) are used to drive the geometric correction algorithms. The system offers extensive capabilities for "shade printing" to aid in the determination of GCPs. Affine, two dimensional least squares polynominal and spacecraft attitude modeling techniques for geometric mapping are provided. Entire scenes or selected quadrilaterals may be rectified. Resampling through nearest …

Stratification Of Landsat Data By Clustering, Marvin E. Bauer, Barbara J. Davis

LARS Symposia

Full realization of the potential advantages of the synoptic coverage provided by Landsat will require the development and use of data analysis techniques which take into account the large variation and diversity of patterns found over many Landsat scenes. Stratification of the scene into units which, are internally homogeneous is recommended as a first step in the analysis of data for whole or multiple frames of Landsat data. The use of clustering as an objective and efficient method of dividing scenes into areas which are spectrally similar (strata) is discussed and initial results, including classification performances and comparison of spectral …

University Education In Remote Sensing: Ill-Defined And Ill-Equipped, Stanley A. Morain

LARS Symposia

Training in remote sensing, like that for chemistry and physics from which it draws, demands a "hands-on" experience by students. Explosive growth in the field over the past decade has left instructors and professors in the untenable position of having inadequate instructional aids. Moreover, the extraordinary breadth of sensor applications, both proven and feasible, has led to almost ad hoc decisions as to what should be included in current course work. This ill-defined and ill-equipped status, in the absence of common denominators, results in students whose training is difficult to assess.

Two recent compilations (Morain, Nealey) summarize the current expanse …

Remote Sensing Technology - A Look To The Future, David Landgrebe

LARS Symposia

If one is bothered by the possibility of being wrong perhaps one of the most risky things to do is to attempt to predict future directions of technology. However, in these days of extremely limited resources, good planning for development is essential to get the greatest bang for the buck spent on technology development. Such a plan must be based upon some anticipation of the direction that development will go. Thus, one must attempt to project both the potential for and direction of the future development of a technology. It is important to know at any given time what one's …

Landsat Signature Development Program, Royce N. Hall, Ken G. Mcguire, Roy A. Bland

LARS Symposia

The LANDSAT Signature Development Program, LSDP, is designed to produce an unsupervised classification of a scene from a LANDSAT tape. This classification is based on the clustering tendencies of the multispectral scanner data processed from the scene. The program will generate a character map that, by identifying each of the general classes of surface features extracted from the scene data with a specific line printer symbols, indicates the approximate locations and distributions of these general classes within the scene.

Also provided with the character map are a number of tables each of which describes either some aspect of the spectral …

Current Methods And Policies Of The Statistical Reporting Service, Charles E. Caudill

LARS Symposia

The Statistical Reporting Service as the, primary fact-collecting and reporting organization of the U.S. Department of Agriculture is responsible for the national program of crop and livestock estimates. Over time, methodology underlying this program has evolved to the point where its foundation is firmly based on probability sampling, employing both area and list sampling frames. Basic data collected for this program is based on voluntary reporting under a pledge of confidentiality. This places strict limits and restraints on SRS in terms of sharing with other agencies or groups the basic data or even unpublished estimates used or generated in the …

Automatic Detection And Classification Of Infestations Of Crop Insect Pests And Diseases From Infrared Aerial Color Photographs, M. Ali, J. K. Aggarwal

LARS Symposia

This paper describes a system designed to analyze aerial color infrared photographs of citrus orchards. The input to the system is a 35 mm transparency of the infrared aerial photograph mounted in a 3-color film digitizer which is controlled by an XDS 930 computer.

An algorithm locates the outline of each individual tree in the photograph and then cluster analysis is applied. For the trees of a transparency, centre of gravity (C.G.) of the set of these trees is determined and then the distance of each individual tree from C.G. is computed by using an empirical distance function which we …
