Ischemic Stroke (IS) is usually initiated due to the neurological shortfall in human brain and which can be recognized by inspecting the periphery of the brain sections. In this paper, a two-step procedure is proposed to extract and evaluate the IS injury from brain Magnetic Resonance Image (MRI). In the initial step, Social Group Optimization and Shannon’s entropy based tri-level thresholding is executed to enhance the IS section of the test image. During the second step, enhanced IS section is then mined using the marker-controlled Watershed (WS) algorithm. The proposed practice is tested on benchmark ISLES 2015 dataset. Performance of the WS segmentation is also verified with the segmentation approaches, like seed-based region growing (SRG) and the Markov Random Field (MRF). The outcome of this study authenticates that, WS provides enhanced picture likeness indices, like Jaccard (90.34%), Dice (94.92%), FPR (7.77%) and FNR (2.65%) compared with SRG and MRF.
