Six studies by the authors in geotechnical image analysis are reported. These were: (a) consistency ratio mapping for tilted scanning electron micrographs of rough surfaces; (b) semi-variance mapping for aerial photographs; (c) mathematical morphology for borehole layouts; (d) computer assistance for borehole logging; (e) the circular Hough Transform for particle shapes; and (f) frame slip. (a) and (b) are methods for textured images. (b) to (e) are aspects of site investigation. (f) is an artefact which might be widespread.
