In order to predict and segment the tumor, many approaches have been proposed. However, they suffer from different problems such as the necessity of the intervention of a specialist, the long required run-time and the choice of the appropriate feature extractor. To address these issues, we proposed an approach based on convolution neural network architecture aiming at predicting and segmenting simultaneously a cerebral tumor. The proposal was divided into two phases. Firstly, aiming at avoiding the use of the labeled image that implies a subject intervention of the specialist, we used a simple binary annotation that reflects the existence of the tumor or not. Secondly, the prepared image data were fed into our deep learning model in which the final classification was obtained; if the classification indicated the existence of the tumor, the brain tumor was segmented based on the feature representations generated by the convolutional neural network architectures. The proposed method was trained on the BraTS 2017 dataset with different types of gliomas. The achieved results show the performance of the proposed approach in terms of accuracy, precision, recall and Dice similarity coefficient. Our model showed an accuracy of 91% in tumor classification and a Dice similarity coefficient of 82.35% in tumor segmentation.<\/jats:p>","DOI":"10.3390\/jimaging7120269","type":"journal-article","created":{"date-parts":[[2021,12,10]],"date-time":"2021-12-10T02:07:18Z","timestamp":1639102038000},"page":"269","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["Brain Tumor Segmentation Based on Deep Learning\u2019s Feature Representation"],"prefix":"10.3390","volume":"7","author":[{"given":"Ilyasse","family":"Aboussaleh","sequence":"first","affiliation":[{"name":"LISAC Laboratory, Department of Computer Science, Faculty of Sciences Dhar El Mahraz, University Sidi Mohamed Ben Abdellah, Fez 30000, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jamal","family":"Riffi","sequence":"additional","affiliation":[{"name":"LISAC Laboratory, Department of Computer Science, Faculty of Sciences Dhar El Mahraz, University Sidi Mohamed Ben Abdellah, Fez 30000, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adnane Mohamed","family":"Mahraz","sequence":"additional","affiliation":[{"name":"LISAC Laboratory, Department of Computer Science, Faculty of Sciences Dhar El Mahraz, University Sidi Mohamed Ben Abdellah, Fez 30000, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hamid","family":"Tairi","sequence":"additional","affiliation":[{"name":"LISAC Laboratory, Department of Computer Science, Faculty of Sciences Dhar El Mahraz, University Sidi Mohamed Ben Abdellah, Fez 30000, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,8]]},"reference":[{"key":"ref_1","first-page":"83","article-title":"Brain tumor segmentation based on random forest","volume":"1","author":"Laszlo","year":"2016","journal-title":"Mem.
