    • A color-mapped display sub,stem efficiently combines palettes of multiple images into a single shared palette. As each image already received a degree of distortion during conventional palette selection, it is desirable to minimize further distortion during the palette combination method of this invention. A pairwise nearest neighbor (PNN) technique is used for combining colors from respective palettes to minimize further distortion. For a final 256-color shared palette, up to 256 (n-1) individual vector merges are performed (where n is the number of image palettes being combined). In one embodiment, two vectors are chosen at each step that yield the lowest increase in distortion when merged. A mean squared error distortion measure of gamma-corrected values defined in YIQ space is used to compare distortion. Searching time at each step is reduced from O(N.sup.2) to O(N), while also eliminating the need for extensive recalculation of color pair distortions between steps. Efficiency is enhanced because the matrix effectively caches distortion calculations between steps. One advantage of the invention is the ability to service run-time demands for the simultaneous display of multiple images on a personal computer or workstation platform having an 8-bit color-mapped display subsystem. Another advantage is the maintenance of image quality across similar multiple images using a shared palette.
    • 颜色映射显示子,干,有效地将多个图像的调色板结合到单个共享调色板中。 由于每个图像在常规调色板选择期间已经接收到一定程度的失真,因此期望在本发明的调色板组合方法期间最小化进一步的失真。 成对最近邻(PNN)技术用于组合各个调色板的颜色,以最小化进一步的失真。 对于最终的256色共享调色板,最多可以执行256(n-1)个单独的矢量合并(其中n是组合的图像调色板的数量)。 在一个实施例中,在每个步骤选择两个向量,其在合并时产生失真的最小增加。 使用在YIQ空间中定义的伽马校正值的均方误差失真测量来比较失真。 每个步骤的搜索时间从O(N2)减少到O(N),同时也消除了在步骤之间广泛重新计算颜色对失真的需要。 效率得到提高,因为矩阵有效地缓存了步骤之间的失真计算。 本发明的一个优点是能够在具有8位彩色映射显示子系统的个人计算机或工作站平台上同时显示多个图像的运行时间需求。 另一个优点是使用共享调色板在类似的多个图像之间维护图像质量。

    • A system for handling incoming media events based on content and state information. An interface which receives events transmitted via a plurality of media forwards such incoming events into an attribute extractor. The attribute extractor extracts one or more attributes from the event and passes those attributes to a characteristic accumulator. The attribute extractor may, for example, read the header of an e-mail event to determine its source or, for example, employ caller ID in conjunction with voice recognition to determine the identity of a caller. The characteristic accumulator creates a characterization of an event on which a decision engine can base a decision of how the event should be handled. The characterization includes all extracted attributes as well as state information deemed relevant to such attributes. The decision engine will typically employ rule-based decision-making using the characterization as a starting point. The decision unit should decide both whether the event should be forwarded and along what outgoing media type. If the outgoing media type is not the same as the incoming media type, appropriate translation is provided.
    • 一种基于内容和状态信息处理传入媒体事件的系统。 接收经由多个媒体传送的事件的接口将这样的传入事件转发到属性提取器中。 属性提取器从事件中提取一个或多个属性,并将这些属性传递给特征累加器。 属性提取器可以例如读取电子邮件事件的标题以确定其来源,或者例如将语音识别结合使用呼叫者ID来确定呼叫者的身份。特征累加器产生一个 决策引擎可以根据事件的处理方式做出决定。 表征包括所有提取的属性以及与这些属性相关的状态信息。 决策引擎通常将使用基于规则的决策作为起点。 决策单元应该决定事件是否应该转发,以及什么传出媒体类型。 如果传出的媒体类型与传入媒体类型不同,则提供适当的翻译。
