Computer Vision 8

Computer Vision relates to the understanding of videos and digital images. It is an interdisciplinary field with a focus on how computers handle images. LiveEdu.tv is a great platform to start learning and improve your computer vision skills with a section dedicated to Computer vision tutorial and resources. Here you can watch how computer vision experts work and use it in your career.

Computer Vision Introduction

Computer Vision relates to the understanding of videos and digital images. Computer Vision is an interdisciplinary field which focuses on how computers handle images or videos. To understand how Computer Vision works, engineers try to understand how the human eyes work.

There are tasks which need to be taken care of in Computer Vision. They include methods for processing, acquiring, analyzing and finally understanding the digital images. Then data are transformed into symbolic or numerical information for easy handling by computers. The image processing enables engineers and scientists to develop a model that can later be used in different fields including medicine, aircraft, sports, etc.

Computer vision is closely connected with Artificial Intelligence as it is used by robots to sense the world around them.

Computer vision is directly connected to how we understand our world around us. We all know how our eyes work, but that doesn’t mean that we are free from any optical illusion. Computer vision tries to cross that boundary or at least match the capabilities of our natural eyes. Computer vision has application over multiple fields including augmented reality, gesture analysis, face recognition, biometrics, agriculture, augmented reality, robotics, security, and many more.

Computer vision is a great field to start a career as it has real-world applications.

History of Computer Vision

Computer Vision history started in the 1960s in universities that were pioneering artificial intelligence. The aim is to mimic the human eye and enable the computers to see the world just like humans. In 1966, scientists and engineers started to gain progress in the field of Computer Vision, and it is believed that they were able to attach a camera to the computer which represented the world quite closely.

Computer vision is different from Digital image processing because it tries to understand the world in 3D rather than simple images.In the 1970s, a lot of-of key algorithms for computer vision were released including the “extraction of edges” from images, non-polyhedra, and polyhedral modeling, labeling of lines, motion estimation, etc.

The next decade saw great improvements in the field of computer vision. The progress came with the help of rigorous mathematical analysis and quantitative aspects. Different process including texture, focus, shading, the concept of scale-space, etc. came into light. The growth continued in the 1990’s when the old topics got more attention.

1990’s also saw the advent of the statistical learning techniques. These techniques are used in recognizing faces. Later on, Computer vision saw higher interaction with different fields such as computer graphics.

The most recent works include the feature-based methods, machine learning techniques, complex optimization frameworks, etc.

Computer Vision Tools

Just like any subfield of artificial intelligence, computer vision is huge and requires tools to work effectively and efficiently. These tools will help you gain an advantage and make work easy. Let us list the best computer vision tools out there. We will only focus on open source tools because they are easy to acquire.

  • OpenCV OpenCV is a computer vision library that falls under the BSD license. It offers C, C++, Java and Python interfaces which support Linux, Mac, Windows, iOS, OS, and Android. The library is designed for maximum efficiency and offers great value when used to developer real-time applications.
  • SimpleCV SimpleCV is an open-source framework for computer vision applications. SimpleCV can also be used to use the OpenCV library and other powerful libraries available. With this, you can try out computer vision without diving deep into learning the file formats, bit depths, buffer management, etc.
  • VLFeat VLFeat is yet another open-source library. It offers popular computer vision algorithms and a clear understanding of extraction and matching.
  • AForge.NET: If you use C# and .NET and want to utilize it in the fields of Artificial Intelligence and Computer Vision, AForge.NET is for you.
  • BoofCV: BoofCV is an open source Java library. It can be used to develop robotics and computer vision applications. It offers high performance and easy to use.
  • Matlab Matlab offers functions, algorithms and apps for simulating and designing the computer vision
