摘要 采用一种Snake模型 ,针对B超心脏图像的高噪声 ,选择并改进与之适应的去噪技术和边缘算子等预处理 ,完成对心室心房的分割 ,从而为提高心室、心房的定量分析精度有重要意义 . Based on a new snake model as well as considering the high noise of ultrasound heart image, suitable filters and edge operators are selected and developed, so that a segmentation algorithm is proposed to segment heart chambers (ventricle or atria), which has great importance for the precision of quantitative analysis.
