Opencv is a open source computer vision library. It is developed for c++ and python. It supports windows, linux, mac, ios. This has many functions that help in image processing. It treat the image as 2D array of pixels. There are functions that changes the coloured image to gray. It helps in object and face detection, edge detection, sharpens and blurres the image etc. It is available free and it has best online support so one can easily use it and learn it. It so many methods that plays with different properties of an image or videos and changes it. Review collected by and hosted on G2.com.

OpenCV is the opensource computer vision library which is available for python and cpp and mostly used in python.There are many things best about opencv such as it is opensource and so it is being contributed by variety of developers to make sure the algorithms are optimistic.On the other hand the great documentation available on its website which makes it easy for a newbie to implement algorithms using opencv.Also it has variety of other resources available on internet in abundance like tutorials so it becomes easy to do anything using openCV.Regarding technical part,it has all the CV algorithms implemented like face tracking,contour finding,thresholding which can easy be used by accessing the library so it is technically sound library.

I have nothing to dislike about this opencv library. Review collected by and hosted on G2.com.

openCV is the computer vision library specially designed for c++ and later on ported to python support also.For python it is the best use of api for computer vision and image processing.You can directly collect the frame from live feed or else the image from the web and do processing on it.Using it you can easily do image manipulations by editing the numpy array because the image is used as the object of numpy array.Also you can easily implement object detection and segmentation using openCV.It is the best api for python for doing image processing.

I have nothing to dislike about openCV.It is the best api a person can have for computer vision processing in python. Review collected by and hosted on G2.com.

C libraries provided for Free to start with the POC, on top of which you can build a product.

The whole documentation is provided on the dedicated site with examples.

The examples provided are in different languages including C, C++, Python, Objective-C, etc.

Most of the problems faced while integration do already have answers present and examples are provided for the same. Review collected by and hosted on G2.com.

Community is smaller.

If you get stuck with some problem faced only by you as a first user, then it may take months to get an answer.

Only good if like minded peoples are around.

Not to be tackled alone. Review collected by and hosted on G2.com.

Supports languages like C++, python. The in built functions help in a big way in implementing real time pedestrian tracking system. Powerful to support in real-time. Review collected by and hosted on G2.com.

Light weight applications are difficult to create as it quite heavy. Review collected by and hosted on G2.com.

As of now i dont have any issue with it. It is the fastes api with a lot of function that makes computer vision and image processing easy. Review collected by and hosted on G2.com.

OpenCV is open source multi language support computer vision library. I am in love with this library, the huge community support makes is so easy to find almost anything from the algorithm details to even solution to small errors on the web. It has been in the market from around 30 years and is still surviving, one can imagine how powerful is it. Review collected by and hosted on G2.com.

I have solved almost all Computer Visions problems using this library and no other substitute is present in the market. No hatred for such a quality library. Review collected by and hosted on G2.com.

- It is open source.

- It has multiple language support, I have used it in C++ as well as python.

- It has all the algorithms one need to perform Computer Vision tasks.

- If I talk specifically for python, the great thing is it easily blends with famous and useful libraries like numpy and matplotlib Review collected by and hosted on G2.com.

It is the only library I rely on for carrying out Computer Vision tasks and the interesting thing is I haven't faced any issue using it as it has a huge community support. Review collected by and hosted on G2.com.

openCV is the library for implementing computer vision algorithms using python.It provides all sorts of algorithms like color masking,color tracking,converting image to gray scale and also you can implement hand recognition using openCV with very less effort.Also it is the well known library and so you can get full support of it online.It is the best CV library for implementing CV algorithms using python.

I like everything about openCV for python but it is not available for python3 and its setup for python2.7 is also a little hasty and difficult task. Review collected by and hosted on G2.com.
