Image retrieval is a process that allows users to find and access images from a large database based on specific queries. This can involve searching by keywords, colors, or even similar images. The goal is to quickly locate relevant images that match the user's needs. The technology behind image retrieval often uses machine learning and computer vision techniques to analyze and categorize images. By understanding the content and context of images, these systems can improve the accuracy of search results, making it easier for users to find what they are looking for in vast collections of visual data.
