A system of microcalcifications detection and evaluation of the radiologist: comparative study of the three main races in Malaysia

This paper uses wavelets in the detection comparison of breast cancer among the three main races in Malaysia: Chinese, Malays, and Indians followed by a system that evaluates the radiologist's findings over a period of time to gauge the radiologist's skills in confirming breast cancer case...
