多重匹配 meaning in English
multimatch
Examples
- There are modifiers to the regular expressions , both inside and outside the expression : case - insensitivity , lookahead , multiple matches , ignoring whitespace , number of matches , and so on
正则表达式中有修饰符，它们既可以在表达式内部也可以在表达式外部：区别大小写、向前查找（ lookahead ） 、多重匹配、忽略空格、匹配的数目等。 - Due to the unique , stable and live physiological properties of the iris and non - invasive to users , most stable and reliable for identification in practical applications of iris - based system , iris recognition is receiving extensive attention and becoming an active topic in biometrics . as an application - oriented research project , iris recognition integrates mathematic , computer science , optics , electronics and physiology etc . based on wavelet transform , aimed to improve the recognition performance , centered at wavelet - based iris feature representation and pattern classification , we review and explore the iris sequence image quality assessment , iris image pre - processing , iris recognition performance evaluation and several other linked topics . we mainly investigate on the principles and application methodology of wavelet transform for iris feature representation and iris pattern classification methods
