binary mask meaning in English

二元掩膜

( 3 ) fabrication methods of planar , y - branches , and channel waveguides employing structure lights formed by cylindrical lenses and optical binary masks are investigated experimentally in detail
对利用柱透镜和光学二元掩模板形成的结构光在光折变晶体中写入平面光波导、 y型光波导以及通道光波导的方法进行了详细的实验研究。
This paper raised a new way for overlapping speech segregation based on sound localization cues . in this paper , we first divide the speech stream into some time - frequency regions and calculate the itd and iid of each region . then the notion of a " time - frequency " binary mask is given , which selects the target if it is stronger than the interference in a local time - frequency region
然后求取每个小片段上的itd (到达双耳时间上的差异性)和iid (到达双耳强度上的差异性)值，经过实验证明某个片段上的itd值和iid值与该片段上的信噪能量比是单调递增关系，因此通过和域值的比较，得出掩蔽系数，来判断每个小片段具体是属于哪个声源。
