The inner structure of a material is called microstructure. It stores the genesis of a material and determines all its physical and chemical properties. However, it is still a big challenge to detect key information in microscopic images fastly and accuratly. In this work, we address the task of grain boundary detection in microscopic image processing and develop a graph-cut based method called Fast-FineCut to solve the problem. Our algorithm makes two key contributions: 1) an improved approach that incorporates 3D information between slices as domain knowledge, which can detect the boundaries precisely, even for the vague and missing boundaries. 2) a local processing method based on overlap-tile strategy, which can not only solve the "chain scission" problem at the edge of images, but save the consumption of resources (such as computational time and memory space), making it possible to analyze the microscopic images with huge resolution.
Python 3 need to be installed before running this scripts. To run this algorithm, you need to install the python packages as follows:
opencv 3
gco(gco_python-master, gco-v3.0)
To install gco, you need to download the gco_python-master and gco-v3.0 at here first, after download, enter the gco_python-master directory, open the setup file and change the gco_directory to your gco-v3.0 directory, and then, run the command:
python setup.py install
We provide 5 test microscopic images in the folder images, including the Original, GroundTruth and Results, the Results includes the detection result of Fast-FineCut algorithm, Wagonner's algorithm and Others.
If you want to run the Fast-FineCut algorithm and Waggoner's algorithm, run the fastFineCutDemo.py, if you want to run the other algorithm, including Otsu, Iteractive, Canny and Adaptive Threshold, run the edgeExtractAllDemo.py, and if you want to run this on your own datasets, you have to change the corresponding image address in those files.
The example results of Fast-FineCut algorithm is shown as follows:
