Segmentation techniques: Region growing and split and merge
Region growing is a procedure that groups pixels or sub-regions into larger regions. Pixel aggregation procedure starts with a set of seed point and from these grows region by appending for each seed point those neighboring pixels that have similar proportion. Region Splitting Merging: In this method an image is first subdivided into a set of ...

2021年5月12日 Clustering is the process of grouping similar data points together and marking them as a same cluster or group. It is used in many fields including machine learning, data analysis and data mining. We can consider segmentation as a clustering problem. We need to cluster image into different object, each object’s pixels has common
