    • One or more portions of a compound image may be classified as picture portions and at least one remaining portion of the compound image may be classified as a non-picture portion. A first layer of a layered image may be generated based on the picture portions of the compound image. The first layer may be compliant with a first image format. A second layer of the layered image may be generated based on the non-picture portion. The second layer may be compliant with a second image format that is different from the first image format. The first layer and the second layer may be sent to a web browser. The first format and the second format may be supported by the web browser.

    • Digital images are resized according to a prescribed image scaling factor. An original image is re-sampled according to the scaling factor, resulting in an initial resized image. A probability of text (POT) map is generated for the initial resized image, where the POT map specifies a smoothed POT value for each pixel in the initial resized image. A weighting factor (WF) map is generated which maps each different smoothed POT value to a particular WF value. The WF map is used to calculate an adjusted luminance value for each pixel in the initial resized image, resulting in a final resized image.
    • 数字图像根据规定的图像缩放因子调整大小。 根据缩放因子重新采样原始图像,导致初始调整大小的图像。 为初始调整大小的图像生成文本(POT)图的概率,其中POT映射指定初始调整大小的图像中每个像素的平滑POT值。 生成加权因子(WF)图,其将每个不同的平滑POT值映射到特定的WF值。 WF图用于计算初始调整大小的图像中每个像素的调整亮度值,得到最终调整大小的图像。

    • The present invention provides a method of establishing a media transmission link for transmitting a large message mode Converged IP Messaging (CPM) message to a group. The method comprises the following steps: Session Description Protocol (SDP) media parameter negotiation is accomplished through session invite messages and success response messages among a transmitter CPM client, a source participation function entity, a controlling function entity, a destination participation function entity and a receiver CPM client; according to the negotiation result, media transmission links are respectively established between the transmitter CPM client and the source participation function entity, between the source participation function entity and the controlling function entity, between the controlling function entity and the destination participation function entity, and between the destination participation function entity and the receiver CPM client. The present invention solves the problem that there is a lack of the MSRP transmission link in the large message mode in the prior art.
    • 本发明提供了一种建立用于向组发送大型消息模式融合IP消息(CPM)消息的媒体传输链路的方法。 该方法包括以下步骤:会话描述协议(SDP)媒体参数协商通过会话邀请消息和成功响应消息在发送方CPM客户端,源参与功能实体,控制功能实体,目的参与功能实体和 接收方CPM客户端; 根据协商结果,在发送方CPM客户端和源参与功能实体之间,源参与功能实体与控制功能实体之间,控制功能实体与目的参与功能实体之间,以及 目标参与功能实体和接收方CPM客户端。 本发明解决了现有技术中在大消息模式中缺少MSRP传输链路的问题。
