    • A method for extracting invisible information from an object in which visible information overlaps with at least part of invisible information formed in stealth ink. The method includes the steps of: irradiating the object with light for making the stealth ink luminous; receiving reflected light from the object; extracting image information from the received reflected light; splitting the image information into a plurality of pieces of color-channel information; obtaining a correlation function between the pixel values of at least two color-channel information selected from the plurality of pieces of color-channel information; reducing a visible information component of selected one of the plurality of pieces of color-channel information to thereby interpolate the color-channel information; and extracting invisible information from the interpolated one piece of color-channel information.
    • 一种用于从可见信息与隐形墨水中形成的至少一部分不可见信息重叠的对象提取不可见信息的方法。 该方法包括以下步骤:用光照射物体以使隐形墨水发光; 从物体接收反射光; 从所接收的反射光中提取图像信息; 将图像信息分割成多条彩色信道信息; 获得从所述多个彩色信道信息中选择的至少两个颜色信道信息的像素值之间的相关函数; 减少所述多个颜色信道信息中的所选择的一个的可视信息分量,从而内插所述颜色信道信息; 以及从内插的一条彩色信道信息中提取不可见信息。

    • A method of invoking power processor element (PPE) serviced C library functions on a synergistic processing element (SPE) running in isolated mode. When the SPE initiates a PPE-serviced function, an SPE stub routine allocates a parameter buffer in an open area of a local store (LS) memory within the SPE. The LS memory includes an open area accessible to the PPE, and an isolated area inaccessible to the PPE. The SPE stub routine copies function parameters corresponding to the PPE-serviced function to a buffer within the open area of the LS memory, and writes a message word, which contains an identification variable of the PPE-serviced function and a location variable of the function parameters, to the open area. When execution is temporarily suspended on the SPE, the PPE reads the message word from the open area of the LS memory and executes the PPE-serviced function.
    • 一种在隔离模式下运行的协同处理元件(SPE)上调用功率处理器元件(PPE)服务C库函数的方法。 当SPE启动PPE服务功能时,SPE stub例程在SPE内的本地存储(LS)存储器的打开区域中分配参数缓冲区。 LS存储器包括PPE可访问的开放区域和PPE无法访问的隔离区域。 SPE存根例程将对应于PPE服务功能的功能参数复制到LS存储器的开放区域内的缓冲区,并写入一个消息字,其中包含PPE服务功能的标识变量和功能的位置变量 参数,到开放区域。 当执行暂停在SPE上时,PPE从LS存储器的打开区域读取消息字,并执行PPE服务功能。
