A Combined Approach on RBC Image Segmentation through Shape Feature Extraction
Algorithm 2
Region growing algorithm.
1. Draw some key points for region growing | Collect the center points and contour points from the extracted contour which is stored in | a XML data file. | 2. Region Growing | 2.1 Set the center point as a seed; | 2.2 Grow the cell from the seed in the way of 4 connectivity neighborhoods till touch certain | point on contour; | 2.3 Store the pixels’ information into a XML file attributed by position and gray level as tree | nodes. | 3. Continue to calculate cell pixels included in next contour | 4. If All cells have been extracted successfully, then exit | 5. Else return 1 |
