Image Segmentation

A computer vision technique that partitions a digital image into multiple distinct regions or segments based on shared characteristics such as color, intensity, or texture. In accessibility applications, image segmentation is used to simplify complex images for tactile conversion by identifying meaningful objects and boundaries that can be represented as raised contours or textured regions on tactile output devices. Segmentation produces cleaner, more interpretable results than simple edge detection because it generates closed contours around distinct regions rather than fragmented boundary lines.
