Region Growing

Region Growing is an image segmentation method. Editprocesstext

In this process, homogeneous image elements are fused into regions. First, the image is divided into initial cells (1 × 1, 2 × 2 or 4 × 4 pixels). Starting with the selection of an initial cell as an initial region, this is then compared with the neighboring cells by means of a criterion (eg the difference between the gray value and that of the neighboring cell). If the criterion is met, the neighbor cell is added to the region. This is repeated recursively, ie the neighboring cells of the newly added cells are also examined. If no neighbors can be added, a region is found.

The process can be repeated for other cells that do not belong to the region until all pixel regions have been assigned. However, depending on the chosen criterion, this can lead to conflicting regions.

The method is vulnerable to "leak", which means that separate regions are captured by small "pixel bridges" as one Weblinks Edit sourcetext
