It is also classified as a pixel-based image segmentation method since it involves the selection of initial seed points. This approach to … See more The first step in region growing is to select a set of seed points. Seed point selection is based on some user criterion (for example, pixels in a certain grayscale range, pixels evenly … See more Advantages • Can correctly separate the regions that have the same properties we define. • Can provide the original images which have clear edges with good segmentation results. See more The main goal of segmentation is to partition an image into regions. Some segmentation methods such as thresholding achieve this goal by looking for the boundaries between regions based on discontinuities in grayscale or color properties. Region … See more Suitable selection of seed points The selection of seed points is depending on the users. For example, in a grayscale lightning image, we … See more • k-means clustering • Watershed (image processing) See more WebImage segmentation is the process of partitioning an image into parts or regions. This division into parts is often based on the characteristics of the pixels in the image. For example, one way to find regions in an image is to look for abrupt discontinuities in pixel values, which typically indicate edges. These edges can define regions. lightning motorcycles corp
