These include:\n\n1. Generation of multidimensional feature spaces from multimodal 'image' data \n(i.e. multiple 'co-registered' 1,2,3, or 4 dimensional data sets, e.g. \nmultiple 'co-registered' time series, multimodal image data, space/time data..) \nvia the use of a set of image templates, including: \n\n - single voxels\n - linear sequences in cardinal directions (ref.)\n - notches in cardinal directions (ref.)\n - light cones in cardinal directions and 45 degree angles (ref.)\n\n2. Clustering methods for generating discrete ('grey') levels from the constructed \nfeature space (the levels are then typically mapped to the original image space at \nthe anchor points of the templates)\n\n3. Building co-occurrence matrices from a discrete level 'image' or a pair of \ndiscrete level 'images', where the discrete level 'images' are typically generated \nvia feature space clustering of the original multimodal data sets (time series, images, \nspace/time data...)\n\n4. Estimation of various complexity/texture measures from the co-occurrence matrices.\n(Haralick measures and epsilon machine related quantities) such as:\n\n - CM Entropy\n - EM Entropy\n - Statistical Complexity\n - Energy Uniformity\n - Maximum Probability\n - Contrast\n - Inverse Difference Moment\n - Correlation\n - Probability of Run Length\n - Epsilon Machine Run Length\n - Run Length Asymmetry\n - Homogeneity\n - Cluster Tendency\n - Multifractal Spectrum Energy Range\n - Multifractal Spectrum Entropy Range\n\n### Documentation\n\nThe documentation on GenTex in hosted [here](https://gentex.readthedocs.io/en/latest/topics/quickstart.html)\n\n### Installation ###\n\n``` bash\npip install gentex\n```\n\n### Who do I talk to?\n\n- Karl Young (original developer)\n- Nicolas Pannetier \n- Norbert Schuff\n\n\n### License\n\nGenTex is licensed under the terms of the BSD license.\nPlease see the License file in the GenTex distribution\n\n\n### References\n\n* K.
