Opencv kmeans segmentation
Web1 de dez. de 2024 · Image segmentation is the process of partitioning a digital image into multiple segments by grouping together pixel regions with some predefined characteristics. Each of the pixels in a region is similar with respect to some property, such as color, intensity, location, or texture.
