Keywords

💡Artificial Intelligence

Artificial Intelligence, often abbreviated as AI, refers to the simulation of human intelligence in machines that are programmed to think like humans and mimic their actions. In the context of the video, AI is central to the theme as it is the driving force behind real-time object detection systems. The script mentions that AI can be associated with complex systems used by large companies, highlighting its significance in modern technology.

💡Real-time Object Detection

Real-time Object Detection is a process where objects within an image or video are identified and tracked as the video is being captured or viewed, without any delay. The video script emphasizes that this technology, once thought to be accessible only to large corporations, can now be implemented by individuals with programming knowledge, showcasing the democratization of AI technology.

💡Neural Networks

Neural Networks are a set of algorithms designed to recognize patterns and are a crucial component of AI. They are inspired by the human brain and are capable of learning from and making decisions or predictions based on data. In the video, neural networks are foundational to the object detection process, where they 'learn' to identify objects by being trained on images.

💡Darknet

Darknet is described in the script as a 'neural network framework for training and testing computer vision models.' It is an open-source tool that allows for the creation and training of neural networks to perform tasks such as object detection. The script positions Darknet as a powerful yet freely accessible resource for those interested in AI and computer vision.
