Symmetric features, both natural and man-made, exist on earth and are visible in spacedata. This paper closely examines one circularly symmetric object, the Robert F. Kennedy stadium in Washington, DC, which is contained in a Landsat-4 Thematic Mapper image. The effect of the space measurement on the appearance of the feature varies according to the band of the image. The human perception of the data is affected by the band and also by the magnification and context of the feature. The differences in interpretability of one object demonstrate the nature of the challenges involved in achieving computer vision. The future computing systems and related developments that may enable a machine to “understand” a symmetric object are described.
