Recently, foreign media exposure of Apple's latest new patent and mdash; use of depth of field information for face recognition, the patent has passed the USPTO approval, and is expected to use the next generation of iPhone's 3D camera system.
It is understood that the patent number 9589177, patented as "the use of depth of field to strengthen the face detection" ralph lauren pas cher, through the computer vision system, the use of specialized hardware and software for face recognition, in particular, has been saved to the database Face data. The patent describes that in a scene, if a plurality of persons are present, facial recognition can be made according to the distance of the person from the distance of the lens, the farther away from the lens, the smaller the surrounding capture frame.
The principle is very simple, the use of special infrared radiation projection to the scene, and then converted into a depth map, and finally through the algorithm to identify. Of course, this program also has some flaws, it does not recognize the differences between the various facial.
It is noteworthy that part of the patent technology from Apple in 2013 acquisition of the Israeli body technology company PrimeSense, the company had Microsoft Kinect provided a 3D sensor and popular, Apple acquired, the industry agreed that its technology will be fast Applied to Apple's own hardware products.
There are rumors that the iPhone 8 will be front 3D camera system, although it is not sure the authenticity of the message, but the emergence of the patent to a certain extent, proved that Apple is developing 3D camera system.
