shape context的一种代码 Shape Context Demo Serge Belongie (sjb@eecs.berkeley.edu) Sept. 4, 2000 1. Information on Chui and Rangarajan data (for demo_1.m) Each filename is of the form save_{fish,chinese,hand}_{def,noise,outlier}_m_n.mat The value of m refers to the test number, n refers to the test example number.  The range of m is 1-5 for deformation and outlier, 1-6 for noise.  The range of n is 1-100. Example: save_fish_outlier_3_2.mat This corresponds to the "fish" shape, outlier test, test no. 3 (out of 5), corresponding to 100% outlier to data ratio, example no. 2. Each file contains the model data (x1), the target data (y2a), and in the case of the noise test, the target data before adding noise (y2). 2. Information on Digit Matching test (for demo_2.m) This uses test data from Yann LeCu
