1) minutiae detection
细节点检测
1.
To improve the performance of a minutiae-based fingerprint verification system,we propose a feature called direction extension vector(DEV) for fingerprint minutiae detection,each item of which can be described as maximum extension distance from a pixel in each pre-defined direction in the sub-region with the same intensity as the pixel.
为了提高基于细节点的指纹鉴别系统的性能,提出了将方向延伸向量特征用于细节点检测,定义方向延伸向量为在预先定义的各个方向上在相同亮度条件下最大延伸长度所组成的向量。
2.
We produce a new method for minutiae detection by following the ridge-line, where the minutiae are extracted directly from the original gray-scale fingerprint images.
提出了一种基于脊线跟踪的细节点检测新方法,它直接从灰度级指纹图像中提取特征点信息,而不必经过二值化和细化过程,从而较大节约了运算时间,提高了可信度。

脆性染色体位点检测法
诊法。亦称脆X染色体检测法。系检测某些智力低下及某些肿瘤病人染色体脆位点的细胞遗传学方法。脆X染色体与智力低下有关。外周血培养及染色体制备法同普通培养,但培养基为缺叶酸(MEMFA)或TC199加氨甲蝶啶(MTX)等,小量小牛血清(一般用5%);pH值为74~75,培 养时间96小时。染色体标本以Giemsa染色后镜检,分析计数。发现标本中有染色体断裂(单体型或染色体型)或脆位点时详细记录。将有脆位点的标本脱油、褪色后,行G及其他有关染色体显带,以确定脆性染色体的区带。
