Digital Enhancement and Restoration of Images Derived from Flow Visualization Experiments

Abstract

The Pixedit program has been rewritten to enable image processing of raster image files residing on the IRIS 4D workstations. Such techniques as spectral filtering, edge detection and enhancement and false colouring techniques have been incorporated into the new version of the program. These techniques are usefully applied in enhancing the quality of photographic images obtained from flow visualization experiments. This report describes the techniques used, giving examples of their application to flow visualization and provides instructions for operating the revised Pixedit program Flow visualization, Digital image processing, Image enhancement.
