The paper deals with the topic of using artificial intelligence technology. Advances in technology are changing the way the world works in hopes of making life better and easier. Visual systems (computer vision and pattern recognition) is the name for the technological and scientific discipline that facilitates the way computers can understand a video or image. The paper explains the concept of artificial intelligence, divides it and lists key characteristics. The concept of soft computing is also described. Then an overview of IT support in the field of artificial intelligence was given. In the continuation of the paper, the program Visual Studio Code and the programming language Python, which were used in the practical part, are described. Two Python programming language libraries are described, Numpy, which is the standard programming language library, and the OpenCV library. In the practical part of the work, the focus was on the possibilities of integrating the OpenCV library for recognizing and marking registered objects. At the end, a program was created that uses a camera as a source of image and video, which enables the computer to see and mark recognized objects.
