HxGN Visual Detection: Machine Learning

AI powered surface inspection

An engineer at a desk using HxGN Visual Detection
HxGN Visual Detection uses CNN (convolutional neural network) deep learning models to train, identify and categorise surface defects. It requires a relatively small quantity of defects samples (in the order of hundreds) to start. As it uncovers undetected defects, the model can be trained to further its ability to identify true positives.

The algorithms in HxGN Visual Detection employ pattern recognition, statistics, deep learning and other image processing techniques to rapidly learn about surface deviations. 

The HxGN Visual Detection machine learning process
 

Deep learning drives greater accuracy

Successful deep learning relies on the depth and sensitivity of the learning model and its environment. HxGN Visual Detection includes a set of models (X-CNN, X-CNN-Tiny, X-CNN-Plus and Segmentation) which are optimised for performance and accuracy. 

The construction of an advanced neural network increases HxGN Visual Detection’s ability to quickly and correctly identify defects, also known as true positives. Powerful algorithms including synthetic image data augmentation, image morphing, normalisation and dimensionality reduction all contribute to this process.

The foundations of these models are based on accepted industry frameworks such as GAN, YOLO, and RCNN.  

HxGN Visual Detection provides an open architecture design that can be easily integrated with custom CNN models. The application is extendable through an API and can be integrated into third party automated manufacturing cells.
