In recent decades, human brain tumor detection has become one of the most challenging issues in medical science. In this paper, we propose a model that includes the template-based K means and improved fuzzy C means (TKFCM) algorithm for detecting human brain tumors in a magnetic resonance imaging (MRI) image. In this proposed algorithm, firstly, the template-based K-means algorithm is used to initialize segmentation significantly through the perfect selection of a template, based on gray-level intensity of image; secondly, the updated membership is determined by the distances from cluster centroid to cluster data points using the fuzzy C-means (FCM) algorithm while it contacts its best result, and finally, the improved FCM clustering algorithm is used for detecting tumor position by updating membership function that is obtained based on the different features of tumor image including Contrast, Energy, Dissimilarity, Homogeneity, Entropy, and Correlation. Simulation results show that the proposed algorithm achieves better detection of abnormal and normal tissues in the human brain under small detachment of gray-level intensity. In addition, this algorithm detects human brain tumors within a very short time—in seconds compared to minutes with other algorithms.

Early tumor detection in the brain plays a vital role in early tumor diagnosis and radiotherapy planning. Magnetic resonance imaging (MRI) is latest technique which normally used for assessment of the brain tumor in Hospitals or scan centers. MRI images are used as the input image for brain tumor detection and classification. For predicting brain tumor earlier, an enhancement feature extraction technique and deep neural network are proposed. At first, the MRI image is pre-processed, segmented and feature extracted using image processing techniques. Support Vector Machine (SVM) based brain tumor classifications were performed previously with less accuracy rate. By using DNN classifier, there will be an improvement in accuracy rate. The proposed method mainly focuses on six features that are entropy, mean, correlation, contrast, energy and homogeneity. The performance metrics accuracy, sensitivity, and specificity are calculated to show that the proposed method is better compared to existing methods. The proposed technique is used to detect the location and the size of a tumor in the brain through MRI image by using MATLAB

Digital image fusion has advanced significantly in governments and civil domains since its introduction in the late 1980s, certainly image fusion of infrared light, materials characterization, remote sensing data fusion, visions segmentation techniques, and brain tumor detection fusion. In medical diagnostics, imaging technology is critical. Because single medical pictures cannot match the demands of diagnostic techniques, which necessitate a huge quantity of data, image fusion study has become a hot subject. Single-mode integration and multi - modal fusion is the two types of medical image processing. Due to the limitations of single-modal fusion's data, many scientists are investigating multidimensional fusion. Brain tumor detection fusion represents the operations of integrating multiple images from imaging modality to formulate fused images with larger volume of data, allowing medical images to be more clinically useful. In this article, we focus on providing a survey of multi-modal image fusion approaches with central focus on novel developments in the domain based on the present fusion approaches, incorporating deep learning fusion approaches. Lastly, this concludes that contemporary multi-modal image fusion study findings are significantly fundamental, and the development trends is on the increase, however there are several hurdles in the study area.
