How to compile and install cvBlob
http://stackoverflow.com/questions/13530054/blobs-with-opencv-which-library-is-best
I have seen these alternatives so far:
- cvBlobs (on google code) -- that is a c library really, working with IplImage so it needs serious adaptation to c++.
- CvBlobsLib (on willowgarage opencv webpage) -- that looks like a c++ library but has quite bad docs with plenty of stuff left unexplained and barely any code example.
- I have seen cv::findContours, cv::moments and cv::drawContours in the OpenCV 2.4.3 library.

我們現在有一個產品，光機構電子硬體成本價就要20000元。然而我們希望能夠在軟體方面節省，所以我們產品的作業系統採用Linux (Tinycore)，開發工具採用QT + QTCreator ，也有使用到函式庫LIBUSB+OpenCV ，因為這些軟體都是GPL授權。那我們可否不用繳任何授權費，直接將我們的產品售出？

OpenCV is released under a BSD license and hence it’s free for both academic and commercial use. It has C++, C, Python and Java interfaces and supports Windows, Linux, Mac OS, iOS and Android. OpenCV was designed for computational efficiency and with a strong focus on real-time applications. Written in optimized C/C++, the library can take advantage of multi-core processing.
Enabled with OpenCL, it can take advantage of the hardware acceleration of the underlying heterogeneous compute platform. Adopted all around the world, OpenCV has more than 47 thousand people of user community and estimated number of downloads exceeding 7 million. Usage ranges from interactive art, to mines inspection, stitching maps on the web or through advanced robotics.
http://answers.ros.org/question/34557/opencv-patent/
I found that some algorithms included in openCV are patented:
SIFT
SURF
I'm not sure if there is any other algorithm patented.
I find this at sift.cpp:
Note that restrictions imposed by this patent (and possibly others) exist independently of and may be in conflict with the freedoms granted in this license, which refers to copyright of the program, not patents for any methods that it implements. Both copyright and patent law must be obeyed to legally use and redistribute this program and it is not the purpose of this license to induce you to infringe any patents or other property right claims or to contest validity of any such claims. If you redistribute or use the program, then this license merely protects you from committing copyright infringement. It does not protect you from committing patent infringement. So, before you do anything with this program, make sure that you have permission to do so not merely in terms of copyright, but also in terms of patent law.
Are this algorithms included in ROS package? Can we use them in commercial applications?
Thank you
The OpenCV license allows its use in commercial applications. However, the SIFT and SURF algorithms are patented. If you use one in a commercial application, you may be open to a patent suit. Here's a pertinent thread from the opencv-users list. If you need to use SIFT or SURF you should protect yourself by contacting the patent owner to find out if you need to pay royalties.
I am not a lawyer, so I'm not going to claim to be 100% correct, but I do know that the purpose of a patent is to ensure that the creator of the work receives proper recognition and compensation for his/her work. My interpretation is such that if you make money using a patented algorithm, you are responsible for compensating the patent holder approrpriately. The patent holder has the right to decide what counts as "fair" compensation. Some patent holders just want to receive credit in the form of a "thank you", but some want money. Only the patent holder can make that decision, since the work belongs to him/her.

Open Source Computer Vision (OpenCV) is an open source computer programming library developed to support applications that use computer vision. It provides hundreds of functions for the capture, analysis, and manipulation of visual data and can eliminate some of the hassle programmers face when developing applications that rely on computer vision. Portions of the library also provide user interface and pattern recognition functions. OpenCV has been employed in both practical and creative applications including self-piloting vehicles and new forms of digital art.
Programming libraries provide common functions or complex capabilities that developers can use in their programs. The OpenCV library contains hundreds of functions that support the capture, analysis, and manipulation of visual information fed to a computer by webcams, video files, or other types of devices. Simple functions might be used to draw a line or other shape on a screen, while the more advanced portions of the library contain algorithms for detecting faces, tracking motion, and analyzing shapes. Many of this library’s algorithms are related to specific uses of computer vision including product inspection, medical imaging, robotics, facial and gesture recognition, and human-computer interaction (HCI). As an open source programming library, OpenCV can be used with very few restrictions in both commercial and hobbyist projects.
With OpenCV, a developer can eliminate some of the complex and tedious work that goes into making computer vision function reliably and focus on building the application. Rather than creating algorithms for facial recognition and the like, a programmer can add just a few lines of code to have a program access the appropriate library function. It also means a programmer does not need to master every aspect of computer vision to build a program that uses it.
In addition to the core video and image processing functionality, OpenCV contains secondary modules intended to support other areas of an application. One of these modules includes machine learning algorithms that can analyze and predict visual patterns. The HighGUI module provides user interface elements as well as functions for storing and accessing video and image files.
The OpenCV library can be found at the heart of some vary ambitious projects. Along with an assortment of sensors, computer hardware, and custom tailored software, it powered a heavily modified sport utility vehicle that navigated a 132 mile (212 km) desert race course without human intervention. Not all projects that rely on the library’s resources are so practical, however. Some members of the creative coding movement, a loose confederacy of people who view programming as a form of expression, have used the library to create new forms of digital art. Others have hacked existing devices containing cameras and opened up new possibilities for gaming, interactive computing, and even telepresence.

- Price: $ 199 USD for a single developer
Work Group License for Windows
Allows for up to 25 developers to install and use Emgu CV for Windows on unlimited workstations for development and to deploy Emgu CV on unlimited clients as per License Terms and Conditions.
- Price: $ 399 USD for the whole work group
=================================================================================
People have been using it in several platforms and devices, and so have I.
The only realiable way I know to distribute an OpenCV application is to build the library yourself and ship the OpenCV binaries along with your application.
There are tools out there that can help you list and retrieve the libraries needed by your app:
- Deploying for Linux? Check this post
- Deploying for Windows? Check this.
=================================================================================
You don't need to install OpenCV in the computers if you don't have permission to do so.
Place the OpenCV libraries and it's dependencies somewhere in the system and before you execute your application make sure you adjust
LD_LIBRARY_PATH to add these paths.
To retrieve the list of dependencies of a certain binary application/library, use
ldd. You might be interested in reading this post: Copying shared library dependencies
1) Install GCC 4.7.3
sudo apt-get update
sudo apt-get install build-essential
2) Install CMake 2.8.10.1
sudo apt-get install cmake cmake-curses-gui
3) Download OpenCV 2.4.5
cd ~/Downloads
tar -xf opencv-2.4.5.tar.gz
cd opencv-2.4.5
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j4
sudo make install
cd ../..
rm -rf opencv-2.4.5*
========================================================================
I have a solution in VS 2010 that calls several OpenCV functions. Now I want to deploy (release) this project to use in another machine that doesn't have OpenCV. I don't want to install OpenCV on the other machine.
I know that I need several dll files, is there any automatic method that can collect all the desired files and put them together with the released .exe file so I can just send/copy this folder ?
