Objectives: A primary brain tumor starts to grow from brain cells, and it occurs as a result of errors in the DNA of normalcells. Therefore, this study was carried out to analyze the two-dimensional (2D) texture, morphology, and statistical featuresof brain tumors and to perform a classification using artificial intelligence (AI) techniques. Methods: AI techniques can helpradiologists to diagnose primary brain tumors without using any invasive measurement techniques. In this paper, we focusedon deep learning (DL) and machine learning (ML) techniques for texture, morphological, and statistical feature classificationof three tumor types (namely, glioma, meningioma, and pituitary). T1-weighted magnetic resonance imaging (MRI) 2D scanswere used for analysis and classification (multiclass and binary). A total of 102 features were calculated for each tumor, and the20 most significant features were selected using the three-step feature selection method, which included removing duplicatefeatures, Pearson correlations, and recursive feature elimination. Results: From the predicted results of multiclass and binaryclassification, a long short-term memory binary classification (glioma vs. meningioma) showed the best performance, withan average accuracy, recall, precision, F1-score, and kappa coefficient of 97.7%, 97.2%, 97.5%, 97.0%, and 94.7%, respectively. Conclusions: The early diagnosis of primary brain tumors is very important because it can be the key to effective treatment. Therefore, this research presents a method for early diagnoses by effectively classifying three types of primary brain tumors.
