124-127 from V. vulpes, Pilisszentkereszt, Hungary, 28. 03. 1966. Hooks of the tapeworms obtained from Parasitological Collection of the Hungarian Natural History Museum were dissected and separated from each other in Berlese medium (Baker and Wharton 1952), while those of other tapeworms were studied in their original condition. They were photographed in profile using a special image acquisition system developed in our laboratory. An Olympus BH-2 microscope was connected with an IBM compatibly PC. A grey scale Panasonic video camera (420 lines) and a high-resolution video digitizing card (760 lines) were used. Photographs were saved in grayscale TIF bitmap 5.0 format. Bitmap objects were filtered and repainted by ImageStar 1.1 graphic software in several steps. After enhancing outlines and removing noises from the images they were converted to black and white TIF bitmap 5.0 format for further computations (Fig. 1A-E). Bitmap files were vectorized using the centerline tracing method of the CorelTRACE program of the commercially available graphics package CorelDRAW. Outlines were calculated by Bézier curve transformation by tracing the drawings by five pixel spaces to eliminate the zigzagged pattern of the outlines and by saving them in dxf file format. Corner and straight line thresholds were five pixels (Fig. IF). Distance measurements of the hooks were generated from five homologous pseudo landmark points of the hooks automatically by a programme written in AutoLISP under the CAD package AutoCAD Release 12 analysing in detail the Dxf files which contained the coordinates of the outlines. In essence, the program carries out the selection of points from an outline named complex entity using a dxf subroutine and four AutoLISP built-in function entsel, entget to obtain the outline and its head, entmod to close the opened polyline (outline), entnext and entget to loop through each vertex (coordinate). Before recording coordinates data of the landmark points and calculating distance measurements the hooks (polylines) were exactly rotated to a horizontal plane using two AutoCAD built-in
