In this paper, we propose a novel approach that uses ConvNet for classifying brain medical images into healthy and unhealthy brain images. The unhealthy images of brain tumors are categorized also into low grades and high grades. In particular, we use the modified version of the Alex Krizhevsky network (AlexNet) deep learning architecture on magnetic resonance images as a potential tumor classification technique. The classification is performed on the whole image where the labels in the training set are at the image level rather than the pixel level. The results showed a reasonable performance in characterizing the brain medical images with an accuracy of 91.16% 2024-05-22T09:50:24Z 2024-05-22T09:50:24Z 2017-12-25 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion peer-reviewed http://hdl.handle.net/10256/18026 info:eu-repo/semantics/altIdentifier/doi/10.3390/app8010027 info:eu-repo/semantics/altIdentifier/eissn/2076-3417 Attribution 4.0 International http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess MDPI (Multidisciplinary Digital Publishing Institute) Applied Sciences, 2018, vol. 8, núm. 1, p. 27 Articles publicats (D-ATC)
