Seed based Region Growing Method", stated to diminish the calculation time required for the segmentation procedure, a seeded region growing strategy is utilized Segmentation is performed trying to lessen the vast measure of data present in a picture to a point where a robotized procedure can perceiveIn this video I explain how the generic image segmentation using region growing approach worksWe provide an animation on how the pixels are merged to createSeed Pixels (Region Growing) Segmentation starts with initial seed point Neighbors of that pixel will be merged if they similar to it Similarity criteria may be defined as intensity or color Process continues till no more similar neighbors found For example next figure shows segmented regions for different seed points

Tool Seeded Region Growing The tool allows one to apply a seeded region growing algorithm to a stack of input features and thus to segmentize the data for object extraction The required seed points can be created with the 'Seed Generation' tool, for example The derived segments can be used, for example, for object based classification Image segmentation using seeded region growing Abstract Image segmentation is the process of clustering pixels into salient image regions (ie) regions corresponding to individual surfaces, objects or natural parts of objects Image segmentation plays a vital role in image analysis and computer vision applications The main topic in the region growing algorithm is the automatic selection of seed points for image segmentation As explained, genetic algorithm is used to select these points automatically Given that in the genetic algorithm, the user can achieve the best possible result by setting its various parameters and checking the results
