The goal of this project is to develop stochastic image analysis and computer vision techniques to obtain accurate volume computation of tumor. Due to complex structures of different normal tissues such the gray matter (GM), white matter (WM), and cerebrospinal fluid (CSF) and abnormal tissues such as cyst, edema, necrosis and scar in the MR brain images, robust measurement of tumor is challenging. We have developed multi-resolution fractal stochastic feature extraction, unsupervised clustering and information theoretic approach to obtain robust tumor segmentation. Currently we have extended our method to segment the multiple brain abnormal tissues (edema, necrosis, enhanced tumor core and non-enhanced core) and ischemic stroke lesions. Participation in multiple Global tissue Segmentation Challenges provided state-of-art comparisons for our tumor and lesion segmentation methods. Our methods ranked 3rd out of 8 in BRATS-2013[1], 4th out of 15 in BRATS-2014[2] and 4th out of 14 in ISLES-2015[3].
