    • In a Converged IP Messaging (CPM) service, an arbitrary terminal generates a message based on a user input, and transmits the message to a CPM server. Upon receiving the message, the CPM server requests a presence server to provide presence information corresponding to a recipient of the message. The presence server searches for presence information corresponding to the recipient in response to the request of the CPM server, and transmits the searched presence information to the CPM server. Based on the transmitted presence information, the CPM server decides to perform interworking for the message, decides a type of a messaging service for interworking, and transmits the message to an Interworking Function (IWF) according to the decided type of the messaging service. The IWF receives the message, converts the message according to the decided messaging service, and transmits the converted message to the recipient.
    • 在融合IP消息传递(CPM)服务中,任意终端基于用户输入生成消息,并将消息发送到CPM服务器。 在接收到消息时,CPM服务器请求呈现服务器提供与消息的接收者相对应的呈现信息。 存在服务器响应于CPM服务器的请求搜索对应于接收者的存在信息,并将搜索到的存在信息发送到CPM服务器。 基于所传送的存在信息,CPM服务器决定执行消息的互通,确定用于互通的消息业务的类型,并根据确定的消息业务类型将消息发送到互通功能(IWF)。 IWF接收消息,根据确定的消息传送服务转换消息,并将转换的消息发送给接收方。

    • Provided are a color to grayscale image conversion method of converting a color image into a grayscale image while maintaining original features of the color image, and a recording medium storing a program for performing the same. When an original color image is input, a target gradient with the features of the input original color image is acquired, and a global mapping function for converting the original color image into a grayscale image is determined based on the acquired target gradient. Thereafter, the original color image is converted into a grayscale image using the determined global mapping function. Therefore, it is possible to quickly convert a color image into a grayscale image, and to acquire a high-quality grayscale image with features of color difference included in the original color image.
    • 提供了一种将彩色图像转换为灰度图像同时保持彩色图像的原始特征的彩色到灰度级图像转换方法,以及存储用于执行该彩色图像的程序的记录介质。 当输入原始彩色图像时,获取具有输入原始彩色图像的特征的目标梯度,并且基于所获取的目标梯度来确定用于将原始彩色图像转换为灰度图像的全局映射功能。 此后,使用所确定的全局映射函数将原始彩色图像转换成灰度图像。 因此,可以将彩色图像快速转换为灰度图像,并且获得具有包括在原始彩色图像中的色差特征的高质量灰度图像。
