|---|---|---|
Single sub-image image segmentation | 8,801,450 | 30,258,006 |
Integration of the center sub-image with the eight adjacent sub-images before image segmentation | 7,970,925 | 31,088,531 |
Segmentation of the eight adjacent sub-images by using the flood fill algorithm image segmentation | 7,082,749 | 31,976,707 |
