Density profiles of biological specimens from Tiff files.
A program for achieving density profiles of Tiff images is described. Densitometric analysis is performed applying a cross-lateral averaging and longitudinal interpolation along the image axis. These procedures may be adapted to a variable axis curvature, length, width and morphological resolution. Since the Tiff format is supported by all desktop scanners and a large number of frame-grabbing devices, the range of applications includes the analysis of light and electron micrographs, autoradiograms, chromatograms, and data from any kind of bidimensional medium or flat surface. A special feature is the possibility of retrieving data from published pictures taken from literature.
