Polynomial models have been adopted as standard analytical tools in imaging metrology for attenuating image distortions for which corrections are applied to image point measurements. A n alternative correction model, the finite element approach, stems from the fact that the displacement of a point in the image plane is projectively equivalent to a proportional change in the principal distance. ...

This paper deals with semi-automatic linear feature extraction from digital images for GIS data capture, where the identification task is pe$ormed manually on a single image, while a special automatic digital module performs the high precision feature tracking in two-dimensional (2-0) image space or even three-dimensional (3-0) object space. A human operator identifies the object from an on-scr...

were first applied to terrestrial concerns throughout the 1970s Abstract (Link and Collins, 1981; Hoge et al., 1983; Krabill et al., 1984). A simple, lightweight, inexpensive, portable airborne laser Over the past 30 years, the technology hasmoved from research profiling system has been assembled from off-the-shelf, comto commercial applications (Baltsavias, 1999). Applications mercially availa...

ZTsing 325-mesh tantalum powder as a contrast medium, it is possible to take high-resolution “radiodermatographs” of man and infra-human primates that combine the advantages of postero-anterior hand radiographs and conventional paper palm-and-finger prints. The radiodermatographs are particularly useful in relating creases, triradii and fingertip ridge patterns to differences in the proportions...

Spatially registered Landsat Thematic Mapper (TM) and SPOT (Systeme Pour I'Observation de la Terre) panchromatic images were merged by combining multiresolution wavelet decomposition components from each, and then reconstructing a merged image using the inverse wavelet transform. Three wavelet merging techniques were compared to the intensityhue-saturation merging technique. The comparison resu...
