An Invisibility Coat Developed in China, Helps in Hiding from Cameras

Invisibility Coat:-
An invisibility coat is a dream for many youngsters and that dream may become a reality. A group of Chinese students invents an invisibility coat that can hide human bodies from security cameras. Hong Kong-based newspaper South China Morning Post (SCMP) reported that the coat is named ‘InvisDefense’. Though it is visible to human eyes, it can blind cameras during the daytime and “emit unusual heat signals at night” to escape recognition from infrared cameras. Invisibility Coat Invisibility Coat SCMP stated that the work of the students has moreover been awarded the 1st prize in a competition by Huawei Technologies Co. Wang Zheng, a professor at Wuhan University, said to SCMP, “the camera captures somebody’s existence but would not be capable to tell if it is a human”. “These days, several surveillance devices could sense human bodies. Cameras on the street have pedestrian recognition functions plus smart cars could identify roads, pedestrians, and obstacles. Our InvisDefense permits the camera to detain you, but it could not tell if you are human,” SCMP stated, citing Wang. Invisibility Coat The coat has a specially designed disguise pattern on its surface which aids it to confuse the detection algorithm of the devices. At night, while cameras sense heat emission or thermal energy and change it to an electrical signal, the coat generates an unusual temperature model to fool it. “The hardest part is the balance of the disguise pattern. Traditionally, scientists used bright images to interfere with machine vision plus it did work. But it stands out to human eyes, making the user even more noticeable,” Wei Hui, one of the members of the research team, said to SCMP. He stated that the InvisDefense cloak presents a “novel” technique of bypassing AI human recognition technology used by present security cameras.  Invisibility Coat When the students tested the coat of on-campus security cameras, the precision of pedestrian recognition decreased by 57 percent. Scientists said that one of the major complexities of evolving the cloak was striking an equilibrium between deceiving both the camera as well as the human eye. The complete set of InvisDefense costs about $70 and includes four temperature control modules along with the cost of printing the pattern. The team hopes the coat will prove its utility as an “anti-drone fight or during a human-machine conflict on the battleground”.
