MRI Brain Images Healthy and Pathological Tissues Classification with the Aid of Improved Particle Swarm Optimization and Neural Network

الملخص EN

The advantages of magnetic resonance imaging (MRI) over other diagnostic imaging modalities are its higher spatial resolution and its better discrimination of soft tissue.

In the previous tissues classification method, the healthy and pathological tissues are classified from the MRI brain images using HGANN.

But the method lacks sensitivity and accuracy measures.

The classification method is inadequate in its performance in terms of these two parameters.

So, to avoid these drawbacks, a new classification method is proposed in this paper.

Here, new tissues classification method is proposed with improved particle swarm optimization (IPSO) technique to classify the healthy and pathological tissues from the given MRI images.

Our proposed classification method includes the same four stages, namely, tissue segmentation, feature extraction, heuristic feature selection, and tissue classification.

The method is implemented and the results are analyzed in terms of various statistical performance measures.

The results show the effectiveness of the proposed classification method in classifying the tissues and the achieved improvement in sensitivity and accuracy measures.

Furthermore, the performance of the proposed technique is evaluated by comparing it with the other segmentation methods.
