LANDSAT 4 investigations of Thematic Mapper and Multispectral Scanner applications

Interband detector noise was suppressed in the TIPS TM North Dakota data by median filtering. Procedures were developed to optimize the visual information content of thematic mapper data and evaluate the resulting photographic products by visual interpretation. A digital to analog TM transfer function was developed which properly placed the digital values on the most useable portion of film response curve. Utilizing the calculated minimum, mean, and maximum and the respective standard deviations of the bands from 50 sample scenes of TM data, look up tables were designed which resulted in acceptable photographic products. These products were evaluated by generation of color composites of selected band combinations using standard photo production procedures, and visual interpretation of scene features

Photographic Assessment of Change in Trichotillomania: Psychometric Properties and Variables Influencing Interpretation

Although photographic assessment has been found to be reliable in assessing hair loss in Trichotillomania, the validity of this method is unclear, particularly for gauging progress in treatment. The current study evaluated the psychometric properties of photographic assessment of change in Trichotillomania. Photographs showing hair loss of adults with Trichotillomania were taken before and after participating in a clinical trial for the condition. Undergraduate college students (N = 211) rated treatment response according to the photos, and additional archival data on hair pulling severity and psychosocial health were retrieved from the clinical trial. Photographic assessment of change was found to possess fair reliability (ICC = 0.53), acceptable criterion validity (r = 0.51), good concurrent validity (r = 0.30–0.36), and excellent incremental validity (ΔR2 = 8.67, p \u3c 0.01). In addition, photographic measures were significantly correlated with change in quality of life (r = 0.42), and thus could be considered an index of the social validity of Trichotillomania treatment. Gender of the photo rater and pulling topography affected the criterion validity of photographic assessment (partial η2 = 0.05–0.11). Recommendations for improving photographic assessment and future directions for hair pulling research are discussed

VIZIR: The SEP high resolution laser beam recorder

A means for high density archiving of meteorological data on a photographic film is described. The data are stored on-line under a form accessible to interpretation. The VIZIR thus forms the final link of the receiving system of a ground station

Medmenham: Anglo-American Photographic Intelligence in the Second World War

The role of photographic intelligence during the Second World War at Royal Air Force (RAF) Medmenham and its predecessor at Wembley is investigated in this thesis. The development from 1939 to 1945 of photographic reconnaissance and photographic interpretation is examined. The growth of the Central Interpretation Unit (CIU) at Medmenham and its change to the Allied Central Interpretation Unit (ACIU) in 1944, with the arrival of a significant American influx is investigated. Medmenham is compared with Bletchley Park using an organisational lens to reveal similarities and differences in the growth and development of these two centralised intelligence organisations. The thesis then explores four case studies: Operation Sealion, the Nazi planned invasion of Britain in 1940, Operation Millennium, the first 1,000 bomber raid of the war in 1942, Operation Chastise, the Ruhr dams raid in 1943 and Operation Epsom, the first large scale operation after D-Day to capture Caen in June 1944. The primary methodology employed is a detailed examination of the photographic interpretation reports produced by Wembley and Medmenham during the operations. The core of the methodology used in this thesis, is an individual examination of every photographic interpretation report produced for each of the case studies. The thesis provides an innovative interpretation of the role and importance of photographic intelligence during the Second World War. It therefore makes an original contribution to intelligence history

Digital enhancement of flow field images

Most photographs of experimentally generated fluid flow fields have inherently poor photographic quality, specifically low contrast. Thus, there is a need to establish a process for quickly and accurately enhancing these photographs to provide improved versions for physical interpretation, analysis, and publication. A sequence of digital image processing techniques which have been demonstrated to effectively enhance such photographs is described

Prospects and problems in designing image oriented information systems

There are slowly maturing and growing about us today a number of techniques which are likely to have a very significant effect upon the implementation of information systems in the near future. One of these techniques is pictorial data handling and interpretation, which is a subclass of the general area called pattern recognition. Pictorial data processing first became volumetrically significant in the case of photographic output of synchrotron bubble chambers which now deliver several million photographs per year. More recently, a surge of interest has developed in automatic interpretation of biological, medical, and weather satellite pictorial data. The automatic scanning of microscopic slides for the purpose of identifying certain morphological characters is an example of a rather complex task in the area of biological/medical laboratory automation. Some new viewpoints have begun to emerge from the experience of grappling with large volume pictorial data handling problems.published or submitted for publicatio

Urban environmental health applications of remote sensing

An urban area was studied through the use of the inventory-by-surrogate method rather than by direct interpretation of photographic imagery. Prior uses of remote sensing in urban and public research are examined. The effects of crowding, poor housing conditions, air pollution, and street conditions on public health are considered. Color infrared photography was used to categorize land use features and the grid method was used in photo interpretation analysis. The incidence of shigella and salmonella, hepatitis, meningitis, tuberculosis, myocardial infarction and veneral disease were studied, together with mortality and morbidity rates. Sample census data were randomly collected and validated. The hypothesis that land use and residential quality are associated with and act as an influence upon health and physical well-being was studied and confirmed
