Apparatus and method for segmenting steel microstructure phase

An apparatus for segmenting a steel microstructure phase, the apparatus comprising:

• a storage configured for storing a machine learning algorithm;
• and
• a processing device configured for segmenting the steel microstructure phase by use of the machine learning algorithm,
• wherein the processing device is configured to:
• receive label data through an input device;
• learn a machine learning model by use of the label data as learning data for the machine learning model;
• segment a phase of a steel microstructure image by use of the learned machine learning model;
• and
• output the segmented result on an output device, and
• wherein an image quality (IQ) value of the label data is normalized to remove a difference in phase shading.
