error position meaning in English

姿式误差

However , there are some problems in the original method , such as low availability of the extracted fragments , error position of the match results , and high complexity of the algorithm etc . in this thesis , a novel method to extract fragments is proposed , and it improves the availability of the extracted fragments ; a novel match method called her is also proposed , which is a hybrid one combining the object ’ s edge and region features , and its advancement is showed in the experimental results ; a prototypal top - down image object segmentation system named io - seg is devised and implemented in this thesis , which is based on class - specific fragment and integrates the methods proposed in this thesis
由于csf - seg方法存在提取的子图可用性差、匹配位置误差大、计算复杂性高等问题,通过深入分析和研究,本文提出了一种新的提取子图的方法,提高了产生的子图的有效性;在深入研究匹配方法的基础上,提出了一种新的结合对象边缘和区域的形状匹配方法? ? her方法,通过实验证明了该方法的优越性;最后,结合文中提出的方法设计并实现了一个top - down的图像对象分割原型系统io - seg 。
