Image analysis refers to the process of extracting information from images or videos. It involves using computer vision techniques and algorithms to identify, detect, classify, measure, and analyze objects or patterns within an image. This can include tasks such as object recognition, facial recognition, optical character recognition (OCR), and more. The goal is often to extract meaningful insights from the visual data that can be used for various purposes, such as surveillance, medical diagnosis, quality control in manufacturing, or even self-driving cars.
