SEMANTIC ANALYSIS

The owner has associated the following topics to the website.

The results of our semantic analysis are shown below using the website's language.

They are the main concepts covered by learnopencv.com.

Each concept has a confidence score. The higher it is, the more important the topic is relative to the page.

Topics
OpenCV Confidence: 92% Arrow up

OpenCV (Open Source Computer Vision) is a library of programming functions mainly aimed at real-time computer vision.

Originally developed by Intel's research center in Nizhny Novgorod (Russia), it was later supported by Willow Garage and is now maintained by Itseez.

The library is cross-platform and free for use under the open-source BSD license.

Machine learning Confidence: 90% Arrow up

Machine learning is the subfield of computer science that, according to Arthur Samuel in 1959, gives "computers the ability to learn without being explicitly programmed." Evolved from the study of pattern recognition and computational learning theory in artificial intelligence, machine learning explores the study and construction of algorithms that can learn from and make predictions on data – such algorithms overcome following strictly static program instructions by making data driven predictions or decisions, through building a model from sample inputs.

Machine learning is employed in a range of computing tasks where designing and programming explicit algorithms with good performance is difficult or unfeasible; example applications include email filtering, detection of network intruders or malicious insiders working towards a data breach, optical character recognition (OCR), learning to rank and computer vision.

Computer vision Confidence: 90% Arrow up

Computer vision is an interdisciplinary field that deals with how computers can be made for gaining high-level understanding from digital images or videos.

From the perspective of engineering, it seeks to automate tasks that the human visual system can do.

CUDA Confidence: 87% Arrow up

CUDA is a parallel computing platform and application programming interface (API) model created by Nvidia.

It allows software developers and software engineers to use a CUDA-enabled graphics processing unit (GPU) for general purpose processing – an approach termed GPGPU (General-Purpose computing on Graphics Processing Units).

The CUDA platform is a software layer that gives direct access to the GPU's virtual instruction set and parallel computational elements, for the execution of compute kernels.

Python (programming language) Confidence: 85% Arrow up

Python is a widely used high-level programming language for general-purpose programming, created by Guido van Rossum and first released in 1991.

An interpreted language, Python has a design philosophy which emphasizes code readability (notably using whitespace indentation to delimit code blocks rather than curly braces or keywords), and a syntax which allows programmers to express concepts in fewer lines of code than possible in languages such as C++ or Java.

The language provides constructs intended to enable writing clear programs on both a small and large scale.
