Computer vision using c++

Does OpenCV use C++?
C++ is a compiled language that offers several benefits over Python for machine learning, such as speed and memory management.
C++ code executes faster than Python code, making it suitable for applications that require high-performance computing..
How to use C++ for computer vision?
Computer vision systems can be programmed to identify certain images or patterns that they have been trained on.
C++ is one of the most popular languages for writing computer vision programs because it offers several advantages over other programming languages such as Python or Java._{Jan 31, 2022}.
Is Python or C++ better for computer vision?
OpenCV is written natively in C++ and has a templated interface that works seamlessly with STL containers..

ncnn

ncnn is a high-performance neural network inference computing framework optimized for mobile platforms. ncnn is deeply considerate about deployment and uses on mobile phones from the beginning of design.

OpenCV

OpenCV (Open Source Computer Vision Library) is a library of programming functions mainly aimed at real-time computer vision.
Originally developed by Intel, it was later supported by Willow Garage then Itseez (which was later acquired by Intel)

PyTorch2Cpp for Using Networks

We are going to give an example from torchvision.models.resnet50(pretrained=True) but you can apply every other network that you customized. (Check ncnn and Onnx supported layers)

PyTorch

PyTorch is an open source machine learning (ML) framework based on the Python programming language and the Torch library.
It is one of the preferred platforms for deep learning research.
The framework is built to speed up the process between research prototyping and deployment.
Can reach official installing C++ distributions of PyTorch from link.
Our installation based on this documentation.

What is a computer vision application?

Computer vision which go beyond image processing, helps to obtain relevant information from images and make decisions based on that information.
In other words, computer vision is making the computer see as humans do.
Basic steps for a typical computer vision application as follows.
What is OpenCV ? .

What is an example of a computer vision task?

For example, changing brightness or contrast is a image processing task which make the image visually pleasing for humans or suitable for further processing for a certain computer vision application.
