From: Automatic detection of anomalies in screening mammograms

  1. §Wavelet basis notation: Dbn where n describes the number of coefficients used in the wavelet. Db2 encodes polynomials with two coefficients, i.e. constant and linear components. Biorm.n where n describes the order for decompositiona and m is the order used for reconstruction.
  2. Suspicious images were passed to the next classifier in the chain.
