Implement otsu-thresholding method. It's useful to create a 2 intensity image.
- Python 3.x (checked Python 3.4.3)
- numpy(checked matplotlib 1.11.0)
- pylab(checked matplotlib 1.5.0)
- OpenCV(checked OpenCV 3.0)
- prepare sample image(.jpg)
- python otsu_threshold.py
original image is as following.
applied otsu method to the original one is as following.
threshold is 128 intensity to create a 2 intensity image.
original image's intensity histogram with static threshold(128) and otsu threshold are as following.
Used 'Adaptive_Gaussian_Thresholoding'. It is included in OpenCV.
