编程:Processing 和 Java 中的 OpenCV 库

| 2013年7月19日

我们可以在 http://ubaa.net/shared/processing/opencv/ 找到 OpenCV Processing and Java Library。

我提供的下载地址: http://yunpan.cn/Q9yQsLF8HjZSc (附带高清版视频操作演示)

网站说明如下

This implementation is not a complete port of OpenCV. Currently, this library supports :

  • real-time capture
  • video file import
  • basic image treatment (brightness, contrast, threshold, …)
  • object detection (face, body, …)
  • blob detection

Future versions will include more advanced functions such as motion analysis, object and color tracking, multiple OpenCV object instances …

For more information about OpenCV visit the Open Source Computer Vision Library Intel webpage, the OpenCV Library Wiki, and the OpenCV Reference Manual (pdf).

由于是国外网站,有些朋友可能打不开,现提供我备份的下载地址: http://yunpan.cn/Q9yQsLF8HjZSc

 另外,最新的库下载地址在这里:https://github.com/atduskgreg/opencv-processing/releases

安装方法:

Installation instructions

1.Begin by downloading and installing the implementation of OpenCV appropriate to your platform:

  • For Windows, download the OpenCV release version 1.0 (not the 1.1pre1) package and follow the instructions of the installer. notes: be sure to select the additional tasks ‘Add ….OpenCV bin to system PATH’ during installation (or you need to add the rigth path by yourself later) and reboot your machine.

  • For MacOS X, dowload the opencv-framework-1.1.dmg image and install the package by following instructions of the installer

 

  • For Linux users, if your distribution doesn’t propose packages in your favorite Package Manager tool, download the latest opencv-*.tar.gz archive and compile/install the source files as describe in the Linux install guide.

2.Download, unzip, and move the OpenCV Processing Library into your Processing libraries folder, or for Java users copy the content of the library folder in one of your Java Extensions folder.

DUE TO AN ERROR WHILE PACKAGING THE ZIP FILE, THIS VERSION UPDATED SHOULD SOLVE THE WINDOWS PROBLEM ABOUT DLL DEPENDENCIES AND OPENCV 1.0

在 Windows 中安装 OpenCV Processing Library
在 Mac 中安装 OpenCV Processing Library

3.Optionally, you can download these OpenCV Processing examples or, for pure Java users, these OpenCV Java samples.

4.Previous library version can be downloaded here

Documentation

  • See the What’s New document for all new implementation or for some of the most important changes
  • Processing documentation … 🙂 start with this page (also include in the OpenCV Processing Library zip archive)
  • For Java users, the Javadoc reference for this project (online only). For offline documentation dowload the OpenCV Java Library API

        按照步骤把OpenCV加进去了,并且也下载了processing3.1.2里面的contributed libraries里面的OpenCV for Processing的这个库文件,在运行样例的时候是没有问题的。但是当我自己新建一个sketch, import这两个文件进去,再打代码的时候还是会报不存在= = 请问这个怎么解决?

        1. TAHO

          我很久没有用这个了。我看了看版本,你试试安装最新版的Processing(目前是3.2),最新的opencv-processing(目前是0.5.2)和最新的OpenCV(最新是2.4.13)。
