先验形状
1.
A new method for segmenting the cardiac MRI image is presented,which is based on object supervision level set method with prior shape information.
提出一种基于目标监督的先验形状level set模型分割心脏MR图像的方法。
4) shape statistics
形状统计

Graph Cuts and Shape Statistics Based Cardiac MR Image Segmentation Using Active Contours Model
基于图划分的形状统计主动轮廓模型心脏MR图像分割
2.
This paper presents a new deformable model using both population-based and patient-specific shape statistics to segment lung fields from serial chest radiographs.
提出一种新的可变形模型,该可变形模型在分割序列X片图像上的肺部区域时,使用了群体和特定病人的形状统计约束。
3.
Based on the detailed analysis of the outer contour,shape statistics Mumford-Shah model is adopted.
文章在详细分析左心室外轮廓的基础上,采用了形状统计Mumford-Shah模型的分割方法,同时对原模型做了如下两点改造:(1)用期望最大(EM)算法求得图像中每点属于心肌的后验概率,通过此后验概率构造“伪灰度”图像来替代原灰度图像,以达到目标与背景灰度呈阶跃型分布的目的;(2)用边缘图替代Mumfor-Shah模型中的梯度项,以增强弱边缘,提高分割精度。
5) prior shape model
先验形状模型
6) elliptical shape prior
椭圆形状先验
1.
Since pedicles were oval-shaped,the elliptical shape prior expressed as the distance between the snake curve and the ellipse was used to constrain the evolution of the snake.
根据椎弓根影近似椭圆形状的特点,将采用距离函数表示的椭圆形状先验信息作为约束力对Snake的形变过程进行约束,其中的约束椭圆通过对初始分割结果进行拟合获得。
