Earlier this year, Edge Impulse released a powerful new learning block that adds anomaly detection to your visual inspection tasks. Previously, this block only included support for the Gaussian Mixture Model (GMM) scoring function. The application of GMM on the feature maps allows for a nuanced detection of irregularities, providing outputs that include not only the presence of an anomaly but also its specific location within the image.
Edge Impulse has now added the PatchCore scoring function to its Visual Anomaly Detection (FOMO-AD) learning block for Enterprise users, enhancing detection accuracy and efficiency for any edge device, from MCU to NPU and GPU.
What is PatchCore?
PatchCore is a state-of-the-art algorithm designed for detecting anomalies by breaking down images into smaller patches. Each patch is compared to a core set of normal patches, allowing PatchCore to catch even small, subtle anomalies that might go unnoticed by traditional methods. This makes it ideal for industries like manufacturing, agricultural, healthcare, and automotive, where even tiny defects can have significant consequences.
Why PatchCore Matters
- Fine-Grained Detection: PatchCore excels at identifying small defects in images, crucial for detailed quality control.
- Fewer False Positives: The core-set selection filters out noise, reducing incorrect anomaly detection and increasing reliability.
- Edge-Friendly Efficiency: Designed for edge devices, PatchCore optimizes anomaly detection without overloading limited resources.
