Deep learning methods gained a huge popularity in segmentation and classification of medical imaging. In this paper we propose a Convolutional Neural Network (CNN) approach which is one of the top performing methods while also being extremely computationally efficient, a balance that existing methods have struggled to achieve, we use this method as a process for segmenting brain tumor regions from magnetic resonance imaging (MRI) using CNNs. The main task for this method is using a public dataset containing 3,064 T1-weighted contrast enhanced MRI (CE-MRI) with different abnormalities from different planes. This novel method of training neural networks on this dataset has proved to be efficient than well-known methods.

Recently, the information processing approaches are increased. These methods can be used for several purposes: compressing, restoring, and information encoding. The raw data are less presented and are gradually replaced by others formats in terms of space or speed of access. This paper is interested in compression, precisely, the image compression using the Haar wavelets. The latter allows the application of compression at several levels. The subject is to analyze the compression levels to find the optimal level. This study is conducted on medical images.

Automated brain tumor detection and segmentation, from medical images, is one of the most challenging. The authors present, in this paper, an automatic diagnosis of brain magnetic resonance image. The goal is to prepare the image of the human brain to locate the existence of abnormal tissues in multi-modal brain magnetic resonance images. The authors start from the image acquisition, reduce information, brain extraction, and then brain region diagnosis. Brain extraction is the most important preprocessing step for automatic brain image analysis. The authors consider the image as residing in a Riemannian space and they based on Riemannian manifold to develop an algorithm to extract brain regions, these regions used in other algorithm to brain tumor detection, segmentation and classification. Riemannian Manifolds show the efficient results to brain extraction and brain analysis for multi-modal resonance magnetic images.
