I couldn't find anything about using OpenCV with AutoHotkey on the internet.
Is there any way to use OpenCV in the ahk?
Disclaimer, I am no expert in AutoHotKey, but I found some resources that describe how to use AHK scripts within Java. This is interesting because you can most definitely use openCV with Java.
I suspect that you can use Java to bridge the connection between openCV and AutoHotKey scripts, creating a final solution that uses openCV and AutoHotKey.
Hope that helps.

I would like to use OpenCV with the Racket programming language. I normally use Python but would like to use Racket so that I can start using it for computer vision projects. However, I do not know how to use/link the OpenCV library with/to Racket. Please could you assist me with this if you know how. Thank you.
Take a look at https://github.com/oetr/racket-opencv/tree/master/tutorials
and https://github.com/tonyg/racket-opencv-videocapture
I have tried neither of them.
The first project has ported some of the Open CV tutorials,
which could a starting point.

I want to know if I download the OpenCV2.4.10, is there the need of JavaCV 0.10 or not, because in the extracted folder of OpenCV2.4.10 inside \OpenCV\build\java there is a Jar file named opencv-2410.jar. I am using Java Language to use OpenCV library. But I also saw JavaCV which can be found at http://bytedeco.org website, when I downloaded all Jars, here I also found named opencv.jar file. Now I don't know what is the deference between them, in Java Language which one is better to use. If use OpenCV2.4.10 is need to JavaCV 0.10? and if use JavaCV 0.10 is need to OpenCV2.4.10? or both of them can be independent used? the If anyone know about this please tell me, Thanks in advance!!
OpenCV library is written in C/C++. Java wrappers are written so that, C/C++ code could be invoked with JNI. JavaCV( unofficial ) and OpenCV( official ) are completely independent java wrappers to use OpenCV from Java.
I suggest you use OpenCV downloaded from offical opencv.org website or from OpenCV github repo(1). Here java wrappers are auto generated during build and so all C/C++ OpenCV functions will have corresponding Java wrappers. This way, every new release or even development versions of OpenCV could be used from Java. This also helps with reading documentation as function parameters matches nearly.
JavaCV is a popular Java wrapper for OpenCV maintained by independent developer(s). It also add helper classes for easier usage. But here, wrappers are not auto generated and so you will need to wait for developers to update to newer versions.
I'm looking into Dart for server-side development and one of the things I'd need to use if I went that direction was LevelDB. There is a port for the JVM that I could use from Java or Groovy but I haven't been able to find anything in Google that points me to a leveldb package for Dart.
I know it's possible to write a native port that uses the C++ API but I'm neither a C++ nor a Dart programmer so while that's theoretically possible, it's out of the question for me personally.
Since LevelDB and Dart are both Google initiatives, surely there's integration somewhere isn't there?
I have written a LevelDB binding for Dart at https://pub.dartlang.org/packages/leveldb. Please try it out and file bugs for any issues you see.
To use LevelDB, which is written in C, you'll need to use the Dart VM's native extensions API. At the time of this writing, there is no open source binding for LevelDB and Dart VM.
Thanks for the question!
I'am developing an eye gaze estimation desktop application for my final year project. I wanted to know what are the main advantages of using javaCV instead of OpenCV ?
OpenCV is a very good Computer visio library. It has C, C++ and Python API. JavaCV is Wrapper of OpenCV using java.
Based on your application you can use native C API using Android NDK. If you are focus on Java then you can use JavaCV.
Also you can have a look at this and some tutorial.
JavaCV is just a non-official Java version of OpenCV.
That said, use JavaCV if you are going to develop in Java, and use OpenCV otherwise.
There is no tutorial for javacv. Sometimes you can't find the curresponding java implementation for Opencv's class(c++ code).Don't get frustrated.Just try to implement it in your own way and open source it.So, others can use it.Be a leader.All the best.
I'm working with C++ (Code::Blocks + OpenframeWorks) and Processing on different projects and have only found the Processing libraries that use the VC++ pre-compiled OpenCV bundle... As I need to use OpenCV with Code::Blocks rather than Visual Studio I was wondering if it is possible to do both?
Side question: I am having trouble compiling OpenCV with Code::Blocks and CMake does anyone have any experience or can point me to a tutorial for the CB 10 + OpenCV 2.3.1 combo?
Thanks in advance.
Best,
Tamler
The official Code::Blocks / OpenCV tutorial can be found here. Have you tried it?
There's also the Compile OpenCV under MinGW tutorial, and you might want to check it out.
