The present disclosure relates to systems and methods for classifying videos based on video content. For a given video file including a plurality of frames, a subset of frames is extracted for processing. Frames that are too dark, blurry, or otherwise poor classification candidates are discarded from the subset. Generally, material classification scores that describe type of material content likely included in each frame are calculated for the remaining frames in the subset. The material classification scores are used to generate material arrangement vectors that represent the spatial arrangement of material content in each frame. The material arrangement vectors are subsequently classified to generate a scene classification score vector for each frame. The scene classification results are averaged (or otherwise processed) across all frames in the subset to associate the video file with one or more predefined scene categories related to overall types of scene content of the video file.

A system and method for controlling navigation of a vehicle carrying hazardous materials includes a control module carried on-board the vehicle storing an information matrix containing hazardous material classifications associated with the identity and location of restricted sites. Each site and material pair has associated with it a control zone around it from which the hazardous material is restricted. The control module includes a positioning device that produces a signal indicating the vehicle's current position, which is compared to the coordinates for the control zones. If the vehicle crosses into a control zone, the system generates a warning to the operator. Further penetration causes the system to order a shutdown of the vehicle engine to prevent further movement.
