Brain Tumor detection using Color-Based K-means Clustering Segmentation
INTRODUCTION
This paper proposes a color-based segmentation method that uses the K-means clustering technique to track tumor objects in magnetic resonance (MR) brain images. The key concept in this color-based segmentation algorithm with K-means is to convert a given gray-level MR image into a color space image and then separate the position of tumor objects from other items of an MR image by using Kmeans clustering and histogram-clustering. Experiments demonstrate that the method can successfully achieve segmentation for MR brain images to help pathologists distinguish exactly lesion size and region.
Color Image Segmentation
The purpose of this project is twofold: To ascertain the superiority of La’b’ color space over the RGB for segmentation in tune with natural perception, and to explore a segmentation technique: Self-Organizing Feature Map (SOFM) , as an alternative to the popular k-means clustering technique. The performance and efficiency of these two color techniques are compared.
SOM Based Image Segmentation
In this paper, a method for segmenting images based on SOM neural network is proposed. At first, the pixels are clustered based on their color and spatial features, where the clustering process is accomplished with a SOM network. Then, the clustered blocks are merged to a specific number of regions. Experiments show that these regions could be regarded as segmentation results reserving some semantic means. This approach thus provides a feasible new
solution for image segmentation which may be helpful in image retrieval.
MRI Brain Image Segmentation Based on Self-Organising Map Network
Magnetic resonance imaging (MRI) is an advanced medical imaging technique providing rich information about the human soft tissue anatomy. The goal of magnetic resonance (MR) image segmentation is to accurately identify the principal tissue structures in these image volumes. A new unsupervised MR image segmentation method based on self-organizing feature map (SOFM) network is presented. The algorithm includes spatial constraints by using a Markov Random Field (MRF) model. The MRF term introduces the prior distribution with clique potentials and thus improves the segmentation results without having extra data samples in the training set or a complicated network structure. The simulation results demonstrate that the proposed algorithm is promising.
