Image segmentation is a technique used in computer vision to partition an image into multiple segments or regions that correspond to different objects or parts of the scene. It involves assigning each pixel in the image to one of several predefined categories, such as object boundaries, background, and foreground. There are various techniques for image segmentation, including thresholding, region-based segmentation, edge-based segmentation, clustering, deep learning, and foundation model techniques. Each technique has its strengths and weaknesses, and the choice of technique depends on the specific application and requirements. Image segmentation is widely used in various fields, such as medical imaging, robotics, autonomous vehicles, surveillance, and agriculture. ```
