Active Contour Model for Brain MR Tumor
Segmentation and Volume Estimation
G. Anand Kumar, P. V. Sridevi
Abstract: Brain MR tumor segmentation and
estimation of volume is a critical task in medical
applications. Brain tumors are analyzed by the common
test method known as magnetic resonance imaging
(MRI) which provides a detail image of brain. The
proposed work involves detection of tumor in brain
using deep learning based active contour model.
Segmentation is the main objective of the proposed
work for achieving detailed information about the
tumor and accurate volume estimation to detect the size
of the tumor. The Euclidean similarity factor (ESF) is
used for considering the spatial distances and intensity
differences of the region there by preserving all the fine
details of the image. 3D convolutional neural network
(3DCNN) is used for extracting the features and
segmentation to identify the tumor location in the
brain. Finally, shoelace method is used to estimate the
volume of the tumor, and it provides treatment planning,
surgical methods, estimation of dose, etc. The
simulation results in this suggested approach could
attain effective performance as compared with the
existing approaches.
Keywords: Brain tumor, Magnetic resonance
imaging, Euclidean similarity factor, Convolutional
neural network.
I. INTRODUCTION
In medical image processing, the segmentation of brain
tumor and analysis of volume estimation is an essential
process focused in research area [1]. Segmentation of
tumor and volume estimation also focused on diagnosis
and treatment planning. From the past decades, cancer is
one of the main diseases that frights the people more.
Brain disease is an important challenging malignant
tumor to cure [2]. So the technology gives more
importance to the estimation of various tumors in brain
by oncologist, neurosurgeons and all medical team, they
needed to identify the entire information and images of
the brain tumors. Moreover the technology associated
with more number of images, can‟t be easily findable by
Surgeons or oncologists. Therefore, there is need for
segmentation.

The segmentation change the characteristics and estimate
the tumor [3]. Solid or active cancer, necrosis and edema
are the different tumor matters which is separated, then it
segments the standard and abnormal tissues. The typical
tissue consist of gray matter (GM), white matter (WM)
and cerebrospinal fluid (CSF)[4]. In brain tumor
segmentation the normal tissue can detect and separate
easily while the abnormal tissue cannot be able to detect
easily. The maximum size of tumor detected in boundary
box is pixel 1-5035, in which the minimum size is 1-1190
[5]. Among past years, the segmentation are taken
through manually, in which physicians and oncologist
handle the segmentation. This manual segmentation face
more problems such as time consuming and inter-intra
rater errors [6]. So automatic or semi-automatic
segmentations are used. In automatic segmentation, the
tumor tissues automatically segmented without the
manual method. The atlas is estimated in the
segmentation with different shapes and locations of
tissues. Voxels are used through Markov Random Fields
(MRF) for smooth segmentation [7]. It also used for the
segmentation of the super voxels. Moreover the voxels
may be mistakenly segment wrong class and locations. To
overcome these Conditional Random Field, and classifier,
are used [8-9].
The automatic brain tumor image segmentation is
classified as edge based segmentation, regions
manipulation segmentation and segmentation by pixel
manipulation. The edge based segmentation consist of
edge detection and active contours, then the region based
is divided as merge/split and graph cut, and the pixel
based is subdivide as thresholding and clustering, along it
divided as global, adaptive, k-means and fuzzy-c means
segmentation respectively [10]. The various techniques
and their algorithm are used for the automatic brain
tumor segmentations. They are given as; Histogram
based method, it‟s an efficient segmentation method
compared to other techniques [11]. Peaks and valleys is
used to locate the clusters in histogram. It also used for
the measurement of dimensions of image pixels. But it
have a limitation as, it is more challenging to find the
insignificant of peaks of segmentation and valleys in the
certain images. Edge based segmentation, detects and
identifies the region of tumor. The edge based
segmentation is a common method and it segment the
boundaries of images [12]. In edge based segmentation the
gray level and color images are used.
