Mao, Statisitcal Pattern Recognition: A Review,\n in preparation\n \n Description\n -----------\n \n This dataset consists of features of handwritten numerals (`0'--`9')\n extracted from a collection of Dutch utility maps. 200 patterns per\n class (for a total of 2,000 patterns) have been digitized in binary\n images. These digits are represented in terms of the following six\n feature sets (files): \n \n 1. mfeat-fou: 76 Fourier coefficients of the character shapes; \n 2. mfeat-fac: 216 profile correlations; \n 3. mfeat-kar: 64 Karhunen-Love coefficients; \n 4. mfeat-pix: 240 pixel averages in 2 x 3 windows; \n 5. mfeat-zer: 47 Zernike moments; \n 6. mfeat-mor: 6 morphological features. \n \n In each file the 2000 patterns are stored in ASCI on 2000 lines. The\n first 200 patterns are of class `0', followed by sets of 200 patterns\n for each of the classes `1' - `9'. Corresponding patterns in different\n feature sets (files) correspond to the same original character.\n \n The source image dataset is lost. Using the pixel-dataset (mfeat-pix)\n sampled versions of the original images may be obtained (15 x 16 pixels).\n \n Total number of instances:\n --------------------------\n 2000 (200 instances per class)\n \n Total number of attributes:\n ---------------------------\n 649 (distributed over 6 datasets,see above)\n \n no missing attributes\n \n Total number of classes:\n ------------------------\n 10\n \n Format:\n ------\n 6 files, see above.\n Each file contains 2000 lines, one for each instance.\n Attributes are SPACE separated and can be loaded by Matlab as\n > load filename\n No missing attributes.
