Automatic defects detection in MR images is very important in many diagnostic and therapeutic applications. Because of high quantity data in MR images and blurred boundaries, tumour segmentation and classification is very hard. This work has introduced one automatic brain tumour detection method to increase the accuracy and yield and decrease the diagnosis time. The goal is classifying the tissues to three classes of normal, begin and malignant. . In MR images, the amount of data is too much for manual interpretation and analysis. During past few years, brain tumor segmentation in magnetic resonance imaging (MRI) has become an emergent research area in the field of medical imaging system. Accurate detection of size and location of brain tumor plays a vital role in the diagnosis of tumor. The diagnosis method consists of four stages, pre-processing of MR images, feature extraction, and classification. After histogram equalization of image, the features are extracted based on Dual-Tree Complex wavelet transformation (DTCWT). In the last stage, Back Propagation Neural Network (BPN) are employed to classify the Normal and abnormal brain. An efficient algorithm is proposed for tumor detection based on the Spatial Fuzzy C-Means Clustering.
- Thresholding method
- K means clustering
- Manual analysis – time consuming, inaccurate and requires intensive trained person to avoid diagnostic errors.
- Difficult to get accurate results
- Not applicable for multiple images for Tumor detection in a short time
- Medical Resonance images contain a noise caused by operator performance which can lead to serious inaccuracies classification.
- ANN-BPN Network for classification
- Fuzzy clustering for tumor detection and structural analysis
- GLCM Feature Extraction
- ANN-BPN Training and Classification
- It can segment the Brain regions from the image accurately.
- It is useful to classify the Brain Tumor images for accurate detection.
- Brain Tumor will be detected in an early stages
- Brain Tumor diagnosis system for medical application
- MATLAB 7.5 and above versions
