    • Methods, apparatus, and computer-readable storage media for tone mapping High Dynamic Range (HDR) images. The HDR image is separated into luminance and color. Luminance is processed according to the parameters to obtain a base layer and a detail layer. The base layer is compressed into a lower dynamic range and the detail layer is adjusted according to the parameters. The compressed base layer, the detail layer, and the color component may be output as separate layers, and various image processing tools and techniques may be applied to the component layers separately to modify the layer(s). One or more tone-mapped images may be generated by merging the modified layers. Thus, each layer of the tone-mapped image may be processed separately using various image processing tools or techniques to modify the output of the tone mapping technique in a wide variety of ways.
    • 用于色调映射高动态范围(HDR)图像的方法,装置和计算机可读存储介质。 HDR图像分为亮度和颜色。 根据参数处理亮度以获得基层和细节层。 基层被压缩成较低的动态范围,细节层根据参数进行调整。 可以将压缩的基本层,细节层和颜色分量输出为单独的层,并且各种图像处理工具和技术可以分别应用于组件层以修改层。 可以通过合并修改的层来生成一个或多个色调映射的图像。 因此,可以使用各种图像处理工具或技术以各种方式修改色调映射技术的输出来分别处理色调映射图像的每一层。

    • Network security is enhanced in a multi-tenant database network environment using a query plan detection module to continually poll the database system to locate and raise an alert for suspect query plans. Security also can be enhanced using a firewall system sitting between the application servers and the client systems that records user and organization information for each client request received, compares this with information included in a response from an application server, and verifies that the response is being sent to the appropriate user. Security also can be enhanced using a client-side firewall system with logic executing on the client system that verifies whether a response from an application server is being sent to the appropriate user system by comparing user and organization id information stored at the client with similar information in the response.
    • 在多租户数据库网络环境中,使用查询计划检测模块来增强网络安全性,以持续轮询数据库系统来定位并提出可疑查询计划的警报。 安全性也可以使用位于应用程序服务器和客户端系统之间的防火墙系统进行增强,记录每个接收到的客户端请求的用户和组织信息,并将其与应用程序服务器的响应中包含的信息进行比较,并验证响应是否正在 发送给适当的用户。 安全性也可以使用客户端防火墙系统进行增强,该系统在客户机系统上执行逻辑,通过比较客户端存储的用户和组织id信息与相似的信息来验证来自应用服务器的响应是否被发送到适当的用户系统 在回应中。

    • A cache server is provided in a network for storing Java objects for retrieval by one or multiple application servers. Application server(s) are configured to request an object from the cache server, rather than requesting the Java object directly from a database, so as to reduce processing load on the database and free up database resources. Responsive to a request for a Java object from an application server, e.g., in an HTTP request, the cache server determines if the object is stored in memory and if so, serializes the requested object and sends the serialized object to the requesting server, e.g., in an HTTP response. The requesting server then deserializes the Java object. If the object is not stored in memory, the cache server instantiates the object (typically by requesting the object from the database), serializes the instantiated object and sends it to the requesting server. Cache coherency methods are also provided.
    • 在网络中提供缓存服务器,用于存储用于由一个或多个应用服务器检索的Java对象。 应用程序服务器被配置为从缓存服务器请求对象,而不是直接从数据库请求Java对象,以减少对数据库的处理负担并释放数据库资源。 响应于来自应用服务器的Java对象的请求,例如在HTTP请求中,缓存服务器确定对象是否存储在存储器中,如果是,则将所请求的对象序列化并将该序列化的对象发送到请求服务器,例如 ,在HTTP响应中。 然后请求服务器反序列化Java对象。 如果对象未存储在内存中,缓存服务器将实例化对象(通常通过从数据库中请求对象),将实例化对象序列化并将其发送到请求服务器。 还提供了缓存一致性方法。

    • A method aligns a character to a sampling grid of an image, where an outline of the character is specified by input pen commands. Points and contours of the input pen commands are determined. An orientation of each contour is determined. A first directed acyclic graph (DAG) is constructed indicating a hierarchical relationship of related contours. Radicals are determined using the first DAG. Simple segments of the contours are determined and merged independently for each radical. Segment pairs and their hinted coordinates are determined. The segment pairs are sorted and a second DAG is constructed for the sorted segment pairs. Collisions between the segment pairs are resolved using the second DAG. The segments pairs, x-free points, and y-free points are fitted to the sampling grid independently for each radical and a result of the fitting is stored in output pen commands.

    • Enhanced systems and methods for processing invoices, payments, and money transfers are described. One aspect of the invention is a computer-implemented method (and corresponding system and computer program product) for determining trustworthiness and familiarity of entities for a billing and payment system, the method comprising: categorizing entities into the following four categories based on their trustworthiness and familiarity to the billing and payment system: (1) a first zone for well-known and trusted entities, (2) a second zone for entities that are familiar but not well-known or not as trusted, (3) a third zone for entities that are new to the billing and payment system, and (4) a fourth zone for other entities; re-categorizing entities based at least on their payment transactions made through the billing and payment system during the time they are with the billing and payment system; and treating the entities of different categories differently according to their categories.
