Opencv

OpenCV is a software toolkit for processing real-time image and video, as well as providing analytics, and machine learning capabilities. Development Benefits. Using OpenCV, a BSD licensed library, developers can access many advanced computer vision algorithms used for image and video processing in 2D and 3D as part of their programs. The algorithms are otherwise only found in high-end image. OpenCV-Python Tutorials是官方提供的文档,其内容全面、简单易懂,使得初学者能够快速上手使用。 2014年段力辉在当时已翻译过OpenCV3.0,但时隔五年,如今的OpenCV4.1中许多函数和内容已经有所更新,因此有必要对该官方文档再进行一次翻译。.

The Open Source Computer Vision Library has 2500 algorithms, extensive documentation and sample code for real-time computer vision. It works on Windows, Linux, Mac OS X, Android, iOS in your browser through JavaScript. Add the following files: opencvcore300.dll, openimgcodecs300.dll, opencvimgproc300.dll, opencvml300.dll, opencvobjdetect300.dll. After adding the files, click on each one in the Solution Explorer and make Content = 'True' Modify you General Properties.

What is OpenCV?

OpenCV is the leading open source library for computer vision, image processing and machine learning, and now features GPU acceleration for real-time operation.

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. Adopted all around the world, OpenCV has more than 47 thousand people of user community and estimated number of downloads exceeding 6 million. Usage ranges from interactive art, to mines inspection, stitching maps on the web or through advanced robotics.

OpenCV Applications

OpenCV is being used for a very wide range of applications which include:

Tif
  • Street view image stitching
  • Automated inspection and surveillance
  • Robot and driver-less car navigation and control
  • Medical image analysis
  • Video/image search and retrieval
  • Movies - 3D structure from motion
  • Interactive art installations

OpenCV Functionality

  • Image/video I/O, processing, display (core, imgproc, highgui)
  • Object/feature detection (objdetect, features2d, nonfree)
  • Geometry-based monocular or stereo computer vision (calib3d, stitching, videostab)
  • Computational photography (photo, video, superres)
  • Machine learning & clustering (ml, flann)
  • CUDA acceleration (gpu)

GPU Acceleration

Over 250 functions have been ported to use CUDA delivering 5x to 100x speed up. Find out more about these on the GPU acceleration project home page.
