EXPLORING NEW POTENTIAL WITH MACHINE LEARNING

Customer-specific algorithms allow Clemex Vision to leap beyond traditional image analysis techniques. Machine Learning (ML) has started to play a key role in enhancing image analysis routines. These new techniques substantially improve the throughput of complex image analysis by further automating traditional threshold-based techniques.

  • Automated Image Analysis
    Take advantage of 30 years of experience in developing routines for various applications in our reputed software.
  • Customer Developed Algorithms
    Clemex integrates, develops and optimizes Python code for customers who wish to use their own methodology.
  • Artificial Intelligence
    New instructions based on machine-learning algorithms are used seamlessly in Clemex Vision 9 or upgraded software.

FASTER AND SIMPLER

The most recent version of Clemex Vision now leverages ML capabilities, including special instructions for martensitic, ferritic, and austenitic grains. These new automatic algorithms are integrated into the existing software’s toolbox to provide a fast and reliable way of optically identifying challenging microstructures.

The impact of machine-learning on existing systems

Clemex customers who have a valid license and a ClemexCare contract can simply update their software and start using the new instructions in the Toolbox. Although their existing workflow remains unchanged, the new ML instructions will make their image analysis routines substantially less complex and therefore a great deal more efficient. Users need only to set the algorithm parameters once, then run the analysis routine on any number of samples.

SET ALGORITHM PARAMETERS

This is usually done once for each type of analysis. The algorithm is powerful enough to take into account light and shading variability. Adjustments are minimal.

 

RUN ANALYSIS ROUTINE

Using our image analysis software is as easy as before. New instructions such as the Martensitic tool are seamlessly integrated into analysis routines.

 

REVIEW YOUR REPORT

Results are available for review onscreen before saving in .xlsx or .pdf format. Data related to each grain can be individually traced and validated.

 

Advantages of machine learning over traditional image analysis techniques

There are two main advantages of routines containing ML algorithms over those using traditional image analysis techniques only. Firstly, it is now possible to detect microstructures that are difficult to analyze optically. For example, martensitc steel is especially hard to analyze because of the materials’ resistance to etching techniques.

In other applications, such as Pearlite-Ferrite Area Percent, ML algorithms greatly simplify the existing image analysis routine. The detection in these applications is no longer done using the Threshold method, which usually requires many fine-tuning instructions, but is performed in a single step which dramatically reduces the time spent on each field. Additionally, fewer user-defined manipulations also mean a more robust routine, which allows for variations in luminosity.

 

  • Simple workflow
    The no-threshold method is a quick and easy way of detecting grain boundaries automatically.
  • Robust
    Repeatable detection of grains without visible boundaries even with light intensity variation
  • Reproducible
    The method minimizes inter-operator variability and increases reproducibility.
  • Accurate
    Successfully tested on hundreds of images in collaboration with a leading industry partner.
  • Fast analysis
    Once the parameters are set, the algorithm is deployed on each field of the sample at high speed.
