The invisibility cloak is the dream of all Potterheads, and that dream may have just become reality because a bunch of Chinese Students invent a low-cost concept cloak that apparently hides the human body The students claim the videos come from security cameras monitored by artificial intelligence. Hong Kong-based newspaper the South China Morning Post (SCMP) reported that the coat, called “InvisDefense”, while visible to the human eye, could blind cameras during the day and “emit an unusual heat signature at night” to evade detection by infrared cameras.

According to the South China Morning Post, the graduate students’ work also won first prize in a competition by Huawei Technologies Co Ltd. Wang Zheng, a professor at Wuhan University who is in charge of the project, told the South China Morning Post that “the camera captures the presence of a person, but cannot tell whether it is a person”. “Many surveillance devices today can detect humans. Cameras on the road have pedestrian detection, and smart cars can identify pedestrians, roads, and obstacles. Our InvisDefense allows cameras to capture you, but it can’t tell if you’re human, Wang was quoted as saying by the South China Morning Post.

The jacket has a specially designed camouflage pattern on its surface that helps confuse the device’s identification algorithms. At night, when the camera detects thermal energy or radiation and converts it into an electrical signal, the cloak generates an unusual temperature pattern to trick it. “The hardest part was the balance of the camouflage pattern. Traditionally, researchers used bright images to interfere with machine vision and it worked. But it stood out to the human eye, making the user more conspicuous,” said a member of the team who worked on the core algorithm. PhD student Wei Hui told the South China Morning Post.
The entire InvisDefense kit costs about $70, which includes four temperature-control modules in addition to the cost of the printed pattern, which the team says is cheap. The team hopes the cloak will prove its usefulness for “counter-drone combat or human-machine combat on the battlefield.”
