Automatic brain portion segmentation from T1 and T2-weighted coronal MRI of head scans using Bond Number and Block Truncation method
K. Somasundaram, Kamalanathan Ezhilarasan · 2012
In this paper we propose a fully automatic method for segmenting the brain portion from the MRI of head scans. We make use of Bond Number (No) to detect the edges of brain and head. Block truncation is used as a filter in edge detected image and finally morphological operations are done to segment the brain portion. The segmented brain portions are compared with the gold standard images provided by the IBSR. Experimental results on a number of MRI volumes show that the proposed method gives satisfactory and comparable results to that of few existing brain extraction method.
