  • Anomaly detection

Minuscule defect recognition technology for image inspections

Enables image inspections that do not miss even small anomalies.


  • Detects minuscule objects in image elements, such as small anomalies arising in appearance inspection images or small suspicious objects captured in security camera footage.
  • In addition to categorizing the presence or absence of an anomaly, the system also detects the anomaly location just by teaching whether an anomaly exists in each training image.

Applications



  • Automatic appearance inspections
  • Video monitoring

Benchmarks, strengths, and track record



  • Using the proposed method, recognition accuracy for minuscule anomalies in 2~16 pixels increased to 67~99 %, compared to 52~79 % using conventional methods
  • Also accurately detects the anomaly location
