Using 3D X-ray technology for the detection of illegal wildlife trafficking

Example of segmentation using scanned CT images of wildlife for algorithm development to produce greyscale images. The colored 3D images are used for visualization only; image segmentations are calculated directly from the reconstructed radiodensity values in grayscale.

A paper titled “Detecting illegal wildlife trafficking via real time tomography 3D X-ray imaging and automated algorithms” and published in Frontiers in Conservation Science, is the first to document the use of 3D X-ray CT scanning technology for wildlife protection in the scientific literature.

This research is a result of detection and conservation agencies; Department of Agriculture Fisheries and Forestry (DAFF), Department of Climate Change, Energy, the Environment and Water (DCCEEW), Rapiscan Systems and the Taronga Conservation Society Australia joining forces to combat the illegal smuggling of wildlife through mail and traveler luggage pathways.

Deputy Secretary of the Biosecurity and Compliance group at DAFF, Chris Locke, and acting Assistant Secretary for Environment Compliance at DCCEEW, Sam Hush said the paper published in the Frontiers in Conservation Science Human-Wildlife Interactions Journal provided the reported results for three wildlife classes (i.e., lizards, birds and fish) within 3D X-ray CT security scan images.

“Illegal wildlife trafficking poses a significant biosecurity risk to Australia as it could introduce pests and diseases that could impact on the environment, as well as human and animal health,” Dr. Locke said.

“This paper demonstrates the boundless potential the 3D X-ray algorithm has in helping to stop exotic wildlife from being trafficked, protecting Australia’s agricultural industries and unique natural environment from exotic pests and diseases.

“This innovative technology is an invaluable complementary platform to our existing biosecurity and wildlife detection tools at Australian international borders, with potential worldwide applications in the future.”

Mr. Hush said wildlife trafficking was also detrimental to Australia’s biodiversity.

“Taking animals from the wild poses risks to the species’ conservation, local populations, habitats and ecosystems, and stopping wildlife from being trafficked into Australia protects our unique natural environment from exotic pests and diseases,” Mr. Hush said.

“It is also extremely cruel. Smuggled animals often suffer stress, dehydration or starvation and many die during transit.

“We have been working with DAFF to test and validate the wildlife 3D X-ray and algorithms which have both proven to be very effective and can help lead to a number of important detections.”
