What is OpenGL and OpenCV?

OpenGL stands for Open Graphics Library. It is a 3D graphic rendering library. OpenCV stands for Open Computer Vision. It is a computer vision library dealing with on real-time image processing. If you want to create 3D images, you use OpenGL.

What can OpenCL be used for?

OpenCL (Open Computing Language) is a framework for writing programs that execute across heterogeneous platforms consisting of central processing units (CPUs), graphics processing units (GPUs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs) and other processors or hardware accelerators.

What is the difference between OpenCL and OpenCV?

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.

Does OpenCV use OpenCL?

As the result the OpenCV-2.4. 3 release included the new ocl module containing OpenCL implementations of some existing OpenCV algorithms. During 3 years more and more functions and classes have been added to the ocl module; but it has been a separate API alongside with the primary CPU-oriented API in OpenCV-2.

What is OpenCL API?

OpenCL™ (Open Computing Language) is a low-level API for heterogeneous computing that runs on CUDA-powered GPUs. In addition to OpenCL, NVIDIA supports a variety of GPU-accelerated libraries and high-level programming solutions that enable developers to get started quickly with GPU Computing.

What is the difference between OpenCL and openopengl?

OpenGL is an API to use graphics accelerators (such as GPUs) for rasterizing scenes fast. the exposed functions are backed by dedicated pipelines in GPUs. OpenCL is an API to use compute-resources of devices in an heterogeneous-computing fashion.

What is openopencv used for?

OpenCV is a computer vision library that uses OpenGL, DirectX, OpenCL, CUDA and many other things so that you can count grains of rice on an image easily. It’s a higher-level layer than OpenGL and OpenCL. 8 clever moves when you have $1,000 in the bank.

What is the use of Compute in OpenGL?

Compute in OpenGL lives to service the graphics pipeline. The only reason to pick OpenGL for any kind of non-rendering compute operation is to support hardware that can’t run OpenCL. At the present time, this includes a lot of mobile hardware. One notable feature would be scattered writes, another would be the absence of “Windows 7 smartness”.

Is GLSL faster than OpenCL/GL?

Their interop with OpenGL is also much faster than OpenCL/GL interop. Even so, compute shaders do not change one fact: OpenCL compute operations operate at a very different precision than OpenGL’s compute shaders. GLSL’s floating-point precision requirements are not very strict, and OpenGL ES’s are even less strict.
