A beacon detection system includes a camera, a motion detection device associated with the camera, and one or more processors. The one or more processors process, using a motion compensation technique, a video feed captured by the camera and determine light flickering frequency information associated with a plurality of regions of the video feed. The one or more processors determine, using a filtering technique associated with a beacon frequency, and based on the light flickering frequency information, a set of one or more regions, of the plurality of regions of the video feed, that are associated with the beacon frequency. The one or more processors provide a filtered video feed that includes video content of the video feed that is only associated with the set of one or more regions of the video feed.

A method of predicting the probability of fracture toughness failure of a metallic part. The method includes receiving static mechanical property data for a metallic part. The method further includes determining a predicted probability of fracture toughness failure for the metallic part using a selected statistical model. The method further includes flagging, to perform fracture toughness testing, the metallic part based on the predicted probability of fracture toughness failure being over a threshold.
