I have some screencasts that explain how to perform a task in a specific software. My objective is to detect where the user clicks on a button or menu item or anything else that leads to a change. One solution to this work is to detect the mouse cursor's location. There are several challenges: The cursor's icon changes and is not always the same in all videos (eg Mac vs Win, arrow sh
我有一些屏幕录像解释了如何在特定软件中执行任务。 我的目标是检测用户点击按钮或菜单项或其他任何导致更改的位置。 这项工作的一个解决方案是检测鼠标光标的位置。 有几个挑战： 光标的图标变化并且在所有视频中并不总是相同的（例如Mac vs Win，箭头形和手形光标）。 我尝试过模板匹配，但是我没有得到好的结果，因为每个捕捉视频的人的显示设置可能不同，因此光标的大小会有所不同。 计算两个后续图像之间的差异可
I have 4 classes: @DatabaseTable(tableName = "bucket") public class Bucket { ... @ForeignCollectionField(eager = true) private Collection<Good> goods; ... } public abstract class Good { ... @DatabaseField(foreign = true, foreignAutoCreate = true, foreignAutoRefresh = true) private Bucket bucket; ... } @DatabaseTable(tableName = "bread") public class Bread

I'm running into significant difficulty getting my mapping file to work with a collection of elements via a foreign key in Hibernate. Java will try to load these files below and won't have any runtime exceptions, but the events table is never loaded as an object of an employee (it will remain null, but every other attribute loads from the DB). In my MySQL database, I have the following:
我遇到了很大的困难，让我的映射文件通过Hibernate中的外键来处理元素的集合。 Java将尝试在下面加载这些文件，并且不会有任何运行时异常，但事件表永远不会作为员工的对象加载（它将保持为空，但从数据库加载其他任何属性）。 在我的MySQL数据库中，我有以下内容： 表：员工 主键：username varchar 名称varchar areacode INTEGER 电话INTEGER 地址号INTEGER addressLocation varchar email varchar 表格：
I want to read XML data using XPath in Java, so for the information I have gathered I am not able to parse XML according to my requirement. here is what I want to do: Get XML file from online via its URL, then use XPath to parse it, I want to create two methods in it. One is in which I enter a specific node attribute id, and I get all the child nodes as result, and second is suppose I just w
我想用Java中的XPath读取XML数据，因此对于我收集的信息，我无法根据我的要求解析XML。 这是我想要做的事情： 通过它的URL从在线获取XML文件，然后使用XPath解析它，我想在其中创建两个方法。 一个是我在其中输入一个特定的节点属性ID，我得到所有的子节点作为结果，第二个是假设我只想获得一个特定的子节点值 <?xml version="1.0"?> <howto> <topic name="Java"> <url>http://www.rgagnon
This is primarily just curiosity, but are there any OCR implementations in pure Java? I'm curious how this would perform purely in Java, and OCR in general interests me, so I'd love to see how it's implemented in a language I thoroughly understand. Naturally, this would require that the implementation is open source, but I'm still interested in proprietary solutions, as I could
这主要只是好奇心，但纯Java中是否有任何OCR实现？ 我很好奇它是如何纯粹用Java来执行的，而且OCR总体上让我感兴趣，所以我很想看看它是如何以我完全理解的语言实现的。 当然，这需要实现是开源的，但我仍然对专有解决方案感兴趣，因为我至少可以检查这种情况下的性能。 我见过一对可以在Java中使用的对象（比如Asprise），但它似乎并不是纯粹的Java实现......有没有？ 我建议在sourceforge.net上尝试Java OCR项目。 我最
I have java application, which makes some job with specific memory usage. I noticed, that when i start application with almost 80% of heap setup for young generation, my applications works much faster then with default 1:2 settings. In particular, I am launching jvm with: java -XX:NewSize=10G -XX:+UseParallelOldGC -server -Xmx12G -Xms12G The server has at least 14 Gb of free physical memory
我有Java应用程序，这使得一些工作具有特定的内存使用情况。 我注意到，当我开始为年轻一代的将近80％的堆设置启动应用程序时，我的应用程序的工作速度比默认的1：2设置快得多。 特别是，我正在启动jvm： java -XX:NewSize=10G -XX:+UseParallelOldGC -server -Xmx12G -Xms12G 服务器至少有14Gb的可用物理内存，所以它应该足够我认为，对于java堆和“其他”空间。 现在事情就是这样发生的： 25.289: [GC [PSYoungGen: 7872
I am trying to implement the above community detection algorithm in Java, and while I have access to C++ code, and the original paper - I can't make it work at all. My major issue is that I don't understand the purpose of the code - ie how the algorithm works. In practical terms, my code gets stuck in what seems to be an infinite loop at mergeBestQ , the list heap seems to be getting la
我正尝试在Java中实现上述社区检测算法，并且在访问C ++代码和原始文件的同时，我无法使其工作。 我的主要问题是我不明白代码的目的 - 即算法的工作原理。 实际上，我的代码陷入了mergeBestQ似乎无限循环的mergeBestQ ，列表heap似乎在每次迭代时都变得更大（正如我期望的那样），但是topQ的值总是返回相同的值值。 我正在测试的这个图很大（300,000个节点，650,000个边）。 我用于实现的原始代码来自SNAP库（https://githu
