title Form Characteristics of Landscape Images: A Landscape Research by Computer Image Processing
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Landscape evaluation research examines how individuals perceive the landscape. Because the amount of the data to describe landscapes is huge, landscape research needs the technology of the computer. This paper describes a method to catch the amount of physical characteristics which were extracted from landscape images by using the technology of the computer image processing and verifies its effectiveness. To do this analysis, we took photographic slides of a landscape sample. Pictures were taken for three regions (the city centre area, the outskirts area, and the farm village area). The number of slides was 6 for each place hence 18 in total were used for theanalysis. Next, we stored these slides on a computer disk. Form characteristics of the landscape elements were extracted by using computer image processing. Borderlines were extracted usingthe algorithm of Robert and were converted into coordinates data by minute line processing and the vector processing. Other elements were extracted by label processing and were converted into the coordinates data by vector processing. These data thus are the vector data for two-dimensions of the image and not the data for a three-dimension space. The processing of these images enables the analysis of the form characteristics in the landscape images. We calculated the data such as appearing length, angle numbers of appearance of the vector data, and analyzed the characteristic of shape and the complexities of landscape applying fractal theory. We compared three districts and were able to find landscape characteristics of various places as a result.
