In this paper, a digital mammogram classification system is presented. The proposed system uses the Discrete Wavelet Transform (DWT) to obtain   features from the input mammogram image. The proposed system suggests a new algorithm for generating the codebook used by the vector quantization (VQ) algorithm to classify the input mammogram (malignant, benign, or normal). The obtained results on the DDSM database indicate the significant performance and superiority of the proposed method in comparison with the state of the art approaches.  Simulation results show that the proposed system achieves a high accuracy and sensitivity.


Keywords :

Medical images; breast cancer; discrete wavelet transform (DWT); vector quantization (VQ); mammogram.
