Region growing segmentation algorithm using python
The algorithm combines the distance between the 3 color spaces ( RGB ) to measure the homogeneity of 2 pixels
( The threshold of a region with a pixel depends on the variance of pixels inside that region )
The choice of the seeds is random
- EXAMPLE TO USE
Command line :
python RegionGrowing.py "imagepath" "maximum threshold possible" ( since the threshold is depenedant on the variance of pixels in a region )
3 examples with the perfect threshold value :
- Unsupervised segmentation
python RegionGrowing.py examples/cat.jpg 10
python RegionGrowing.py examples/mri.jpg 15
python RegionGrowing.py examples/apple.jpg 12
- Supervised segmentation
python RegionGrowingSV.py examples/apple.jpg 12
The image will popup :
1-left click with the mouse to choose all the seeds
2-right click with the mouse when you finish choosing the seeds so the algorithm starts
