Abstract
The present invention discloses a method for automatically detecting a nasal tumor from the MR (magnetic resonance) images. First, the pixels that have specific trends and are affected by contrast agents with specific level will be filtered according to the developing coefficient and control coefficient of grey prediction. Then the tumor area would be detected by using Fuzzy C-means clustering technique to distinguish the differences between normal tissue and tumor. Owing to the work of grey prediction, calculation in the Fuzzy C-means clustering technique can be dramatically reduced and the result of tumor detection is enhanced.
