Abstract
Medical images have a crucial place in the medical diagnosis. As a
specific part of medicine, Magnetic Resonance Imaging (MRI) has become a
useful modality since it provides plentiful information and high sensitivity. The
rapid growth of MRI technology results in increasingly amount of MRIs which
have to be efficiently stored, analyzed and described. By improving these
processes, the decision making process for the clinicians is getting easier.
In this paper we apply the Edge Histogram and the Region-based Shape
descriptors standardized by MPEG-7 standard to MRIs. We have used 13917
MRIs provided by ImageCLEF 2008. Experimental results showed the Edge
Histogram Descriptor achieves higher precision. We have also combined both
descriptors by averaging their output ranks. Analysis showed that averaging the
output ranks leads to higher precision. However, the obtained results and the
fact that MRIs have specific characteristics suggest that additional image
processing techniques have to be used.
