医学图像中感兴趣区域ROI (Region Of Interest)通常包含重要的信息,对医生分析和诊断具有重大的意义,所以ROI检测是医学图像处理与分析的重点。本文结合数字乳腺图像特点,运用机器学习方法和图像处理技术,针对数字乳腺图像的肿块识别提出一种基于Cascade结构的ROI检测方法。该方法将代价敏感的分类算法和Cascade结构有效地结合,具有高敏感性和高效率。实验结果表明该方法能有效检测出乳腺图像中的肿块ROI,与基于像素的方法相比计算量小、效率高;与基于区域的方法相比避免了直接使用传统的图像分割和滤波技术难以有效检测ROI的问题。

Hairstyle is an important feature of virtual human character in computer ***, which is an important part of hair modeling, is aimed to model the shape of static hair. It'sdifficulty to ensure both hair realism and real-time performance due to the huge number of hair strandsand the complexity of hairstyles. Besides, human-computer interaction should also be considered. Thus,hairstyling still remains a challenging task. Generally, to support hairstyling effectively, it's crucial forhairstyling tools to find a tradeoff between realism and interaction.
