Astrocyte

AI Training Made Simple and Cost Effective

No-Code AI training tool to quickly deploy AI models for machine vision solutions. Tackle tough inspection cases traditional methods can't handle.

Teledyne DALSA Astrocyte empowers users to harness their own images of products, samples, and defects to train neural networks to perform a variety of tasks such as anomaly detection, classification, object detection, and segmentation. With its highly flexible graphical user interface, Astrocyte allows visualizing and interpreting models for performance/accuracy as well as exporting these models to files that are ready for runtime in Teledyne DALSA Sapera and Sherlock vision software platforms.

Why AI?

Traditional Machine Vision Tools

✗ Confuse water droplets and surface damage
✗ Can’t handle shade and perspective changes
✗ Miss subtle surface damage

AI Classification Algorithm

✓ Ignores water droplets
✓ Is robust to variations in surface finish and perspective
✓ Can detect a full range of defects

No AI expertise or code required

Train a model without having to learn about any AI parameters
Simply choose one of three tuning depth options (low, medium, high), and easily get an optimized AI model
Graphical user interface for rapid machine vision development
Train AI models quickly (under 10 minutes with good data)

Save time labelling images and training

Continual learning allows for updating of classification models on the factory floor without retraining. This saves hours of time updating models.
Automatic labelling (Via SSOD or pretrained models) generates bounding boxes and labels
Import existing label sets (.txt, PASCAL VOC, MS COCO, KITTI))
Segmentation annotation with different shapes (polygon, rectangle, circle, torus tools)
Decrease training effort with pre-trained AI models (less samples required)

Combine with other Teledyne components

Leverage Teledyne’s Sherlock or Sapera Processing to get the best of rule-based algorithms combined with AI models for a full solution
Live video acquisition from Teledyne and third-party cameras

Key Features

Graphical User Interface for rapid machine vision application development.
Automatic tuning of training hyperparameters for maximum ease-of-use for non-experts in AI (also a manual mode for experts)
Automatic generation of annotations via pre-trained models or semi-supervised training
Masking of regions to exclude from inspection via ROI markers of multiple shapes.
Highly accelerated inference engine for optimal runtime speed on either GPU or CPU
Continual Learning (aka Lifelong Learning) in classification for further learning at runtime.
Location of small defects in high-resolution images via tiling mechanism.
Easy integration with Sapera Processing and Sherlock vision software for runtime inference.
Assess AI models via visual tools such as heatmaps, loss function curves, confusion matrix.
Full image data privacy – train and deploy AI models on local PC.

Application Examples

Astrocyte significantly improves quality, productivity, and efficiency in X-ray medical imaging

The tiny and random nature of fibers on X-ray detectors make them challenging and time consuming for traditional methods or humans.

With Astrocyte, the X-ray solutions team was able to rapidly identify all defects and even outperform their operators.

Surface inspection on metal plates

Classification of good and bad metal sheets. Tiny scratches on metal are detected and classified as bad samples. Astrocyte detects small defects on high resolution images of rough texture. Just a few tens of samples are required to train a good accuracy model. Classification is used when good and bad samples are available, while Anomaly Detection is used when only good samples are available.

Location/identification of wood knots

Localization and classification of various types of knots in wood planks. Astrocyte can robustly locate and classify small knots 10-pixels wide in high-resolution images of 2800 x 1024 using the tiling mechanism which preserves native resolution.

Detection/segmentation of vehicles

Detection and segmentation of various types of vehicles in outdoor scenes. Astrocyte provides output shapes where each pixel is assigned a class. Usage of blob tool on the segmentation output allows performing shape analysis on the vehicles.

Deep Learning Architectures

Astrocyte supports the following deep learning architectures.

Classification

Description
A generic classifier to identify the class of an image.

Typical Usage
Use in applications where multiple class identification is required. For example, it can be used to identify several classes of defects in industrial inspection. It can train in the field using continual learning.

Anomaly Detection

Description
A binary classifier (good/bad) trained on “good” images only.

Typical Usage
Use in defect inspection where simply finding defects is sufficient (no need to classify defects). Useful on imbalanced datasets where many “good” images and a few “bad” images are available. Does not require manual graphical annotations and very practical on large datasets.

Object Detection

Description
An all-in-one localizer and classifier. Object detection finds the location of an object in an image and classifies it.

Typical Usage
Use in applications where the position of objects is important. For example, it can be used to provide the location and class of defects in industrial inspection.

Segmentation

Description
A pixel-wise classifier. Segmentation associates each image pixel with a class. Connected pixels of the same class create identifiable regions in the image.

Typical Usage
Use in applications where the size and/or shape of objects are required. For example, it can be used to provide location, class, and shape of defects in industrial inspection.
