摘要：The brain tumors are the mass of undifferentiated cells which undergoes uncontrolled proliferation of cells inthe brain. Segmentation of these tumors is more difficult than natural. Because their functional sensitivity is higher thanother images. Many different algorithms have been proposed for segmentation of these type of tumors in brain images.In this paper, we propose an approach in order to improve efficiency of the brain tumor segmentation through theminimax optimization that applies to the thresholding of the MRI brain image to segment tumor. The tumorsegmentation is performed by the implementation of an optimistic technique called variational minimax optimization.The proposed system uses search of optimum threshold with an iterative line search technique with faster executiontime of 15 seconds.
