Considering the influence of more random atmospheric turbulence, worse pointing errors and highly dynamic link on the transmission performance of mobile multiple-input multiple-output (MIMO) free space optics (FSO) communication systems, this paper establ
提出了一套基于指势的识别系统,引入OPENCV计算机视觉库,为系统软件的设计及实现提供了便捷的代码。不同于以往方法依赖于正对摄像头(垂直)投影的限制,该系统能够在任意倾斜角度情况下进行指势识别。其基本方法包含肤色检测、大量连续微移动(Consecutive Count of Micro Movements,CCMM)算法和图像降噪及轮廓提取的预处理部分,然后运用k值法进行指尖及指蹼点的检测。最后,
A technical feasibility of autofluorescence ductoscopy in breast milk ducts as blood vessels phantoms has been assessed as successful. Malignant tumor can be clearly identified through the milk ducts. We also present the operation principle as well as the
