Pattern recognition (PR) is the technology of making a decision on a concrete object which category it belongs to PR can be used to solve many problems in understanding complex systems One of its applications is the comprehension and analysis of biomedical magnetic resonance spectroscopy data Previous studies using high-resolution liquid NMR spectroscopy have shown that the levels of metabolites in biological samples change with the time after pathological or other perturbation PR can be used not only to identify...

Pattern recognition (PR) is the technology of making a decision on a concrete object which category it belongs to PR can be used to solve many problems in understanding complex systems One of its applications is the comprehension and analysis of biomedical magnetic resonance spectroscopy data Previous studies using high-resolution liquid NMR spectroscopy have shown that the levels of metabolites in biological samples change with the time after pathological or other perturbation PR can be used not only to identify the differences of the pathological from the normal, but also to find which bio-fingerprints result in such differences, thus supplying valuable information for diagnosis In this review, various statistical PR methods used in biomedical magnetic resonance spectroscopy are discussed, and the latest progresses in this field are introduced

模式识别(PR)是把具体事物进行正确归类的科学, 它能解决许多对复杂体系的认识问题. 生物医学核磁共振波谱(NMR)的理解和分析便是其中一种. 在受到病理或者其他刺激后, 生物体内的代谢物水平会发生变化, 这种变化可以通过液体高分辨核磁共振的手段来观察. 模式识别把这种认识进一步深化, 不仅可以将正常状态与病理状态区分开, 还能找到是哪些生化指纹导致两种状态的差异, 为生理、病理和药理等研究, 以及临床诊断提供依据. 模式识别与生物核磁共振波谱的结合, 已经发展成为代谢组学研究的关键技术, 甚至被称为基于核磁共振的代谢组学. 主要讨论适用于生物医学核磁共振中的模式识别方法及其最新进展.

Mumford-Shah model,which has better ability to segment images, had been used to segmenting images or tracking targets.But it needs computing all the data of the image constantly during the iterative course,so it is not suitable for real-time application for its low efficiency.Aiming at this disability,by using the characteristic of the MRI,a fast method of solving the M-S model is improved based on the histogram method.This method first construct a signed table,which can be used to distinguish the area inside or outside of the edges,and use the histogram method to get the rough results,then use the searching method to optimize the results and get the final edges.Experimental results show that the new model can get the better results in an efficient way.

Mum ford-Shah(MS)模型因为其具有良好的图像分割能力,目前已被广泛应用于图像分割、目标跟踪等领域。但是由于其迭代过程需要对所有图像数据反复进行计算,因而其时间效率很低,难以实时应用。针对这个缺点,根据医学核磁共振图像(MR I)的特点,对M-S模型进行了改进,提出了一种基于直方图的快速求解方法,其求解时,首先构造符号表,以区分曲线内外区域;然后利用直方图法来进行目标的快速粗分割,再通过遍历优化边界,来获得较精确的分割。对MR图像进行的分割实验表明,其分割效果更好,同时,时间效率也有大幅提高,这就方便了实时应用。
