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
