Graduate level text book for researchers and students working with earth materials. Proceeds by worked examples using typical Earth Sciences imagery from awide range of sources (digital photography, light and electron microscopy, etc.). Focusses on image analysis, extraction of objects (segmentation), analysis of shape and size distributions, fabric analysis (particle and surface fabrics), texture analysis, orientation imaging (optical and EBSD). Features separate text boxes with background information, theory, etc.. Based on free software Image SXM. Introduces image analysis in the earth sciences, applicable to the full range of images generated from digital photography, light and electron microscopy Much needed book for working oceanographers as well as university teaching programmes Based on free software Image SXM INDICE: 1 - Images Image acquisition - Data check - Pre-processing - Look-up Tables. 2 - Segmentation by point operations Bitmap - Structural filtering - Volume determination - Error of volume analysis (Basic stereology) 3 - Grainsize distributions From distribution of spheres to circles - From 2-D to 3-D - Grain size mapping 4 - Fractal grain size distributions Magnification cascades - Grain size distribution mapping 5 - Analysis of particle cross sections Primary descriptors - Shape factors - Best fit ellipse - Analysis of ellipses 6- Raster to vector Points on a grid - Digitization - Orientation artefacts - Reconstruction of outlines 7 - Particle fabrics Particle projections - Orientation distributions - Bulk fabric - Strain analysis 8 - Surface fabric Surface projections - Strain test / interpretation - Rose diagrams - Surface orientation distributions 9 - Shape of individual particles New shape descriptors: Convexity / Concavity - Angularity 10 - Spatial distribution Random - clustered - anticlustered - Volume and Surface model - Significance test 11 - Segmentationby neighbourhood operations Smoothing filters - Gradient filters - Exporting contours 12 - Frequency analysis Spatial frequencies - Fast Fourier Transforms- Frequency filtering 13 - Autocorrelation analysis 2-D Autocorrelation function - Shape and size -Local and bulk fabric 14 - Test images Generating outlines - Library of images - 2-D test images - 3-D Voronoi tesselations 15 - Orientation Imaging Optical orientation imaging - Orientation images - Converting EBSD input data - Pole figures 16 - Misorientation Images Misorientation images- Misorientation profiles - Orientation tracking 17 Orientation gradients Orientation gradient images - Defect structures - Histograms.
