OpenCV grouping white pixels

I've done the hard work, turning my iSight camera on my MacBook into an infrared camera, converted it, set the threshold etc.. and now have an image that looks something like this: alt text My problem is now; I need to know how many blobs are on my image by grouping the white pixels. I don't want to use cvBlob / cvBlobsLib , I'd rather just use what is already in OpenCV. I can

OpenCV将白色像素分组

我已经完成了艰苦的工作,将我的MacBook上的iSight摄像头转换为红外摄像头,转换它,设置阈值等等。现在有一个图像,看起来像这样: 替代文字 我现在的问题是; 我需要通过对白色像素进行分组来了解我的图像上有多少个斑点。 我不想使用cvBlob / cvBlobsLib ,我宁愿使用OpenCV中已有的东西。 我可以遍历像素,并通过检查(阈值)触摸白色像素来对它们进行分组,但是我猜测OpenCV中可能有这么简单的方法吗? 我猜我不能

Maze solving with constraints

I know solving mazes is a frequently discussed topic here on Stack Overflow. Here is a problem that might interest you all. A maze in the form of an*n matrix will be given as input. Each element would lie between 0-9. A sequence of numbers, each between 0-9 again would also be given. The dimension of the matrix and the sequence array is also known. The question is to find all possible path

迷宫解决约束

我知道解决迷宫问题是Stack Overflow中经常讨论的话题。 这是一个可能让你感兴趣的问题。 一个* n矩阵形式的迷宫将作为输入给出。 每个元素将介于0-9之间。 也会给出一系列数字,每个数字在0-9之间。 矩阵和序列阵列的维度也是已知的。 问题是要找到满足给定序列的从(0,0)到(n-1,n-1)的矩阵中所有可能的路径。 路径只能向下或向右移动。 必须使用线程来完成。 输入和输出格式如下所示 - 示例:示例1 http://g

c#

I want to compare the contrast of several images, for that purpose I need to measure the contrast. In fact I need the local contrast, not global. I already have a solution which just compares the neighboring pixel of each image pixel. The results are ok, but now I need to compare it with another algorithm which I do not understand. It is mentioned in this paper from Peli: http://www.eri.harva

C#

我想比较几张图片的对比度,为此我需要测量对比度。 事实上,我需要的是当地的对比,而不是全球。 我已经有了一个解决方案,它只比较每个图像像素的相邻像素。 结果是好的,但现在我需要将它与另一个我不明白的算法进行比较。 本文来自Peli:http://www.eri.harvard.edu/faculty/peli/papers/ContrastJOSA.pdf,它被称为“带限对比度”。 我理解它是这样的:将图像传送到频率空间并应用低通滤波器。 好。 应用频率范围为+1

Move a rectangle using angles

I need to move a rectangle using angles. Actually I want to change the direction of my moving rectangle when it reaches the location I have given in my code in if statement! I just need the way I can find out how to move my rectangle at 60, 30, 60, 120, 150, 270 degrees! Suppose that if circle.Y>=this.Height-80 See this: I really actually need to change the direction of rect

使用角度移动矩形

我需要使用角度移动矩形。 实际上,我想在我的代码中给出的位置在if语句中更改我的移动矩形的方向! 我只需要我能找到如何在60,30,60,120,150,270度移动矩形的方式! 假设如果 circle.Y>=this.Height-80 看到这个: 我真的需要改变使用角度的矩形运动的方向! 以便在某个位置达到我可以根据我自己选择的角度更改矩形方向! 这样: if(circle.Y>=this.Height-80) move in the direction of 90 deg

Documenting descriptions on Complex Types

Within my API I'm trying to document the different field descriptions, however none of attributes seem to work. I know this functionality is supposed to have been recently implemented within WebAPI 5.1 (running WebAPI.HelpPage 5.1.2). ASP.Net Web API Help Pages: Document Model Data Annotations - Work Item 877 I'm trying to document both my response model: And the individual fields/

记录复杂类型的描述

在我的API中,我试图记录不同的字段描述,但是没有任何属性看起来可行。 我知道这个功能应该是最近在WebAPI 5.1中运行的(运行WebAPI.HelpPage 5.1.2)。 ASP.Net Web API帮助页面:文档模型数据注释 - 工作项目877 我试图记录我的响应模式: 和个人领域/属性 我已经尝试了XML注释,DataMember和Display属性的混合,但似乎没有找到。 /// <summary> /// blah blah blah /// </summary> [DataContract(Name

Made one instance of a class equal to another. – How to cancel that?

I have: instance1 = instance2; how do I disconnect them from one another, so that altering one will not affect the other? EDIT: I want them referencing the same object (so I can't clone), and later – not. But I still want both instances of the class – so I can't 'null' them. Thanks EDIT: myclass a = new myclass(); a.integer = 1; myclass b = new myclass(); b.integer = 2;

创建一个与另一个类相同的实例。 - 如何取消?

我有: instance1 = instance2; 我该如何将它们彼此断开连接,以便更改一个不会影响另一个? 编辑:我想他们引用相同的对象(所以我不克隆),后来 - 不是。 但我仍然需要这个类的两个实例 - 所以我不能'空'它们。 谢谢 编辑: myclass a = new myclass(); a.integer = 1; myclass b = new myclass(); b.integer = 2; a = b; //All changes to one will affect the other, Which is what I want. //<Mo

copy a class, C#

Is there a way to copy a class in C#? Something like var dupe = MyClass(original). You are probably talking about a deep copy (deep copy vs shallow copy)? You either have to: implement (hard code) a method of your own, try to implement (or find) an implementation that uses Reflection or Emit to do it dynamically (explained here), use serialization and deserialization to create a deep c

复制一个类,C#

有没有办法在C#中复制类? 像var dupe = MyClass(原创)。 您可能正在谈论深层复制(深层复制vs浅层复制)? 您必须: 实施(硬代码)你自己的方法, 尝试实现(或查找)使用反射或发射动态地实现它的实现(在此解释), 如果对象标有[Serializable]属性,则使用序列化和反序列化来创建深层副本。 public static T DeepCopy<T>(T other) { using (MemoryStream ms = new MemoryStream()) {

Difference between the System.Array.CopyTo() and System.Array.Clone()

System.Array.CopyTo()和System.Array.Clone()之间有什么区别? The Clone() method returns a new array (a shallow copy) object containing all the elements in the original array. The CopyTo() method copies the elements into another existing array. Both perform a shallow copy. A shallow copy means the contents (each array element) contains references to the same object as the elements in the origin

System.Array.CopyTo()和System.Array.Clone()之间的区别

System.Array.CopyTo()和System.Array.Clone()之间有什么区别? Clone()方法返回包含原始数组中所有元素的新数组(浅拷贝)对象。 CopyTo()方法将元素复制到另一个现有数组中。 两者都执行浅拷贝。 浅拷贝意味着内容(每个数组元素)包含与原始数组中元素相同的对象的引用。 深层副本(这两种方法都不会执行)会创建每个元素对象的新实例,从而生成一个不同的但相同的对象。 所以区别是: 1- CopyTo require to have

What exactly happens call async method without await keyword?

I have a web server and there is a periodic job merges and send records (lots of request logs). Task.Run(() => { while (true) { try { MergeAndPutRecords(); } catch (Exception ex) { Logger.Error(ex); } } }); In MergeAndPutRecords function, there are code merging records and async function returns Task sending

究竟发生了什么,而不是等待关键字调用异步方法?

我有一个Web服务器,并有定期作业合并和发送记录(大量的请求日志)。 Task.Run(() => { while (true) { try { MergeAndPutRecords(); } catch (Exception ex) { Logger.Error(ex); } } }); 在MergeAndPutRecords函数中,有代码合并记录,异步函数返回任务发送记录。 (显然它是亚马逊Kinesis Firehose的PutRecordBatchAsync。)

Trouble understanding async and await

I've been trying to understand async/await and Task in C# but have been failing spectacularly despite watching youtube videos, reading documentation and following a pluralsight course. I was hoping someone might be able to help answer these slightly abstract questions to help my brain out. 1.Why do they say that async/await enables an 'asynchonrous' method when the async keyword o

麻烦理解异步并等待

我一直在尝试理解C#中的异步/等待和任务,但尽管观看了YouTube视频,阅读文档并遵循复数视图课程,但仍然失败壮观。 我希望有人能够帮助回答这些稍微抽象的问题来帮助我解决问题。 1.为什么当async关键字自己什么都不做,并且await关键字添加一个暂停点时,他们说异步/等待会启用“asynchonrous”方法? 不增加一个强制方法同步动作的暂停点,即在继续之前完成await标记的任务。 2.显然,除了事件处理函数外,您不应该使用
