    • A method of measuring a similarity between images is provided. The method includes the steps of (a) computing a statistical dissimilarity between the images; (b) computing a perceptual dissimilarity between the images; and (c) computing a dissimilarity between the texture features of the images based on the statistical dissimilarity and the perceptual dissimilarity. When images perceptually similar to a query image are searched and retrieved according to the above measuring method, the possibility that the retrieved images are not perceptually similar to the query image is small. Accordingly, the image searching performance can be improved when searching images having texture features similar to that of a query image.
    • 提供了一种测量图像之间的相似度的方法。 该方法包括以下步骤:(a)计算图像之间的统计学不相似性; (b)计算图像之间的知觉差异; 和(c)基于统计学上的不相似性和感知不相似性来计算图像的纹理特征之间的不相似性。 当根据上述测量方法搜索和检索与查询图像感知相似的图像时,检索到的图像在听觉上与查询图像不相似的可能性较小。 因此,当搜索具有与查询图像相似的纹理特征的图像时,可以提高图像搜索性能。

    • Integrated trace selection and profiling in dynamic optimizers may include selecting a trace head based on profile of basic blocks that are executed. The basic blocks executed from the trace head may be recorded as a trace. The trace may be added to a trace nursery in non-compiled state. The trace may be interpreted and profiled until the trace matures. Under a profiling mode, path sensitive runtime information such as values, types, targets of call-sites, and exit frequencies can be collected. The trace may be moved out of the nursery to a compilation queue in response to determining that the trace has matured based on an execution count of the profiled trace.
    • 动态优化器中的集成跟踪选择和分析可能包括基于执行的基本块的轮廓选择跟踪头。 从跟踪头执行的基本块可以记录为跟踪。 踪迹可以添加到非编译状态的跟踪托儿所。 跟踪可能被解释和分析,直到跟踪成熟。 在分析模式下,可以收集路径敏感的运行时信息,如值,类型,呼叫站点目标和退出频率。 响应于确定跟踪已经基于分析跟踪的执行计数而成熟,跟踪可以移出苗圃到编译队列。

    • An execution trace of building blocks of computer code includes a head building block at which the execution trace starts, and a tail building block at which the execution trace ends. The building blocks are executable in a sequence from the head building block to the tail building block. The execution trace is truncated at a particular building block of the execution trace, which becomes the tail building block. The particular building block can correspond to a head building block of an additional execution trace, and/or to a loop header building block of a loop within the execution trace and at which the loop is entered. The execution trace is a compilation unit on which basis a trace-based compiler computer program generates an executable version of the code at least by compiling these units.
    • 计算机代码的构建块的执行跟踪包括执行跟踪开始的头构建块和执行跟踪结束的尾部构建块。 构建块可以从头部构造块到尾部构造块的顺序执行。 执行跟踪在执行跟踪的特定构建块处被截断,这将成为尾部构建块。 特定构建块可以对应于附加执行跟踪的头部构造块,和/或对应于执行跟踪内的循环的循环头部构造块,并且进入循环。 执行跟踪是一个编译单元,在该基础上,基于跟踪的编译器计算机程序至少通过编译这些单元来生成代码的可执行版本。
