Image segmentation is a computer vision technique that involves dividing an image into multiple segments or regions. This process helps in identifying and isolating different objects or areas within an image, making it easier to analyze and understand the content. By breaking down an image into smaller parts, image segmentation allows for more precise tasks such as object detection, recognition, and tracking. It is widely used in various applications, including medical imaging, autonomous vehicles, and image editing, enhancing the ability to process visual information effectively.
