Abstract:
In medical image processing, segmentation of the
internal structure of brain is the fundamental task. The
precise segmentation of brain tumor has great impact on
diagnosis, monitoring, treatment planning for patients.
Various segmentation techniques are widely used for brain
Magnetic Resonance Imaging (MRI). The aim of this paper
presents an efficient method of brain tumor segmentation.
Morphological operation, pixel extraction threshold based
segmentation and Gaussian high pass filter techniques are
used in this paper. Thresholding is the simplest approach to
separate object from the background, and it is an efficient
technique in medical image segmentation. Morphology
operation can be used to extract region of brain tumor. This
system converts the RGB image to gray scale image and
removes the noise by using Gaussian high pass filter.
Gaussian high pass filter produced sharpen image and that
improves the contrast between bright and dark pixels. This
method will help physicians to identify the brain tumor before
performing the surgery.
