A Study on the Identification of the Three-Dimensional Impression on the Urban Space With the Two-Dimensional Map-Data

Abstract

An approach of the technique to evaluate the impression of the three-dimensional space and proof of the effectiveness are performed from the two-dimensional (2D) map-data. The binary format-image of the building and the blank space led spatial frequency (Gray value) with an image from the map-data of six areas, and furthermore, by performing the Fourier transform for spatial frequency (Gray value), the characteristics are analyzed. The break-down into patterns by the cluster analysis has been run with the extractions of the Gray Value, which appears as a result of the analysis, and the features in every area. This result also proves that the resultant corresponds with the resultant of the impression evaluation of the three-dimensional space that used a "walk-through" cartoon film (or animation).
