日本电信电话公司(NTT)的信息通信网研究所开发出一种高速提取物体轮廓及其构成线段(方向性线段)的新的光处理方式,比以往的电子处理快2个数量级。该方式采用新开发的强介电性液晶空间光调制器的“轮廓增强特性”,可将物体图像的亮暗交界部分作为轮廓线迅速提取出来,进而,通过光学空间滤色提取轮廓中任意方向的构成线段。 系统的构成如图1所示。所采用的强介 NTT’s Information and Communication Network Research Institute has developed a new method of light extraction that extracts body contours at high speeds and composing line segments (directional segments), two orders of magnitude faster than previous electronic processing. This method uses the newly developed “ferroelectric liquid crystal spatial light modulator” contour enhancement feature, the object can be bright and dark boundaries of the image as a contour line quickly extracted, and further through the optical spatial color filter to extract the outline of any direction The composition of the line. System structure shown in Figure 1. Used by the strong referral
