    • An apparatus and a method of calculating a channel frequency domain correlation are disclosed in the invention. The apparatus of calculating the channel frequency domain correlation includes: a pilot channel preliminary estimation unit configured to preliminarily estimate a frequency domain channel response at pilot subcarriers of a receiving signal to obtain a pilot channel preliminary estimation value; a determination unit configured to determine a channel frequency domain correlation value which can be reliably calculated; a first channel frequency domain correlation value calculation unit configured to calculate the channel frequency domain correlation value which can be reliably calculated using the pilot channel preliminary estimation value to obtain a reliably calculated channel frequency domain correlation value; and a second channel frequency domain correlation value calculation unit configured to calculate an other channel frequency domain correlation values using the reliably calculated channel frequency domain correlation value. The invention may also effectively apply to calculation of the channel frequency domain correlation and channel estimation.

    • The invention relates to method for deriving a sub-right from a right, the right comprising a plurality of components, each of which specifies an aspect of the right. A component may be, for example, a principal, an action, a resource, and a condition. The invention also relates to a method for integrating a first right with a second right. Furthermore, the invention relates to a method of sharing rights by deriving a sub-right from a right, allowing use of the sub-right, and integrating the sub-right with the right. In addition, the invention relates to a system to support rights sharing by enabling the derivation of a sub-right from a right, the right comprising plural components each of which specifies an aspect of the right, the system comprising a receiving module for receiving a sub-right, the sub-right comprising plural components each of which specifies an aspect of the sub-right, and a confirmation module for confirming that the values of the components of the sub-right can be derived from the values of the corresponding components of the right. The invention further relates to a method for deriving a sub-right from a pool of rights granted by a grantor to a grantee for controlling use of resources within a computing environment, the computing environment having a mechanism for enforcing rights within the environment to control use of resources in accordance with the rights.

    • A method and a system for updating a background model based on depth are disclosed. The method includes receiving, in response to the occurrence of a predetermined background updating condition, one or more depth images captured after a time when the predetermined background updating condition occurs; obtaining, based on an original background model, foreground images in the one or more captured depth images, which are newly added compared with a depth image at the time when the predetermined background updating condition occurs; for each of foreground pixels in each of the newly added foreground images, comparing a current depth value with a previous depth value before the time when the predetermined background updating condition occurs; and updating, when the current depth value is greater than the previous depth value, the original background model as the updated background model by using the foreground pixel in the newly added foreground image.
    • 公开了一种基于深度更新背景模型的方法和系统。 该方法包括响应于预定的背景更新条件的发生,接收在预定的背景更新条件发生之后捕获的一个或多个深度图像; 基于原始背景模型,获得与所述预定背景更新条件发生时的深度图像相比新添加的所述一个或多个捕获的深度图像中的前景图像; 对于每个新添加的前景图像中的每个前景像素,将当前深度值与预定背景更新条件发生之前的先前深度值进行比较; 并且通过使用新添加的前景图像中的前景像素,将当前深度值大于先前深度值的原始背景模型更新为更新的背景模型。
