基于归一化割的颅脑MRI肿瘤提取算法
Brain MRI Tumor Extraction Algorithm Based on Normalized Cut
摘要
Abstract
It is difficult to accurately extract the brain tumor,because of the low contrast of brain Magnetic Resonance Image(MRI),the blur tumor edge and complicated brain tumor shape. Order to solve this problem,this paper puts forward the algorithm cmbcaused normalized cut with active contour model based on the slsh wessure Force ( SPF ) function to extract brain MRI tumor. It uses active contour model based on the SPF function to convergent the normalized cut extraction tumor edge,setts the convergence of the iterative number and smooth coefficient to control the MRI tumor edge convergence speed and shape, and makes the tumor edge curve to stop at the real tumor edge. Simulation results show that ths algorithm can overcome the tumor extracting negative impact of tumor shape changing and tumor contrast, and extracts the brain tumor stably and accurately.关键词
