A computer engineering student from Bahia has managed to come up with a technological solution to a problem that plagues most fans of the reality show. Brother Brazil From Rede Globo: How do I know which of the 38 cameras of the live show is your favourite?
Tired of using his laptop to monitor his chosen attendees and manually switch cameras, Jequié (BA) resident 23-year-old Rafael Azevedo created an application programming interface (API) that works as an extension of Google Chrome. The app uses facial recognition to automatically switch cameras when the tracked participant goes to another room in the guarded house.
How does the BBB22 face tracker work?
On LinkedIn, Rafael explained how the technology works. According to the post, which reached 30,000 reactions, the software developer explains that the extension uses a technique called web scraping (data scraping, free translation) from the BBB page on Globoplay. Using the streaming service for computers and laptopsThe API obtains the frames of the program in real time by manipulating the data from the cameras.
With every BBB22 comic (thumbnail) available, the fan began to delve deeper into face recognition and design an artificial intelligence algorithm through the MTCNN framework, FaceNet, and the SVM vector machine. The result was a predictor of participants. about 98% hit when performing verification and automatic camera switching.
Speaking to the “Tilt” notebook WowRafael said that although he uses the Python programming language and builds the functionality for his personal use, the buzz of the news led him to analyze the costs to make it possible to offer the extension on the Chrome Web Store.
