Does Apple charge for sending animal expression text messages?

Emoticons are the same as ordinary messages, and pictures are charged according to MMS, but MMS function needs to be enabled.

The security of face recognition can be used as authentication. Apple uses 3D structured light technology. Through the front infrared camera and Dot Project components, iPhone X can quickly scan people's faces and form 30,000 invisible IR points on the face surface, just like 3D modeling.

The advantage of this is that no matter how your hairstyle changes, whether you wear glasses or a hat, iPhone X can still recognize your face and unlock it smoothly, no matter day or night.

Moreover, in order to better analyze the collected data, Apple also built its own neural network according to the capabilities of A 1 1 chip, which provided sufficient computing power for face recognition, thus making the process of face entry and unlocking smooth and fast.

At the same time, Apple also provides absolute protection for users' facial data to ensure security. Apple's brand-new face recognition technology is actually the previously reported "3D structured light dual camera" technology. Its principle is based on actively emitting specific infrared structured light to illuminate the measured object, thus obtaining the three-dimensional image data of the portrait.

3D structured light is a way to obtain 3D images. Many times, the image we see is on a plane, and we don't know the depth corresponding to each point. While the 3D image obtains the color and depth of each position of the photo. The concept of structured light is to isolate some specific objects or patterns by emitting an invisible grating from a light source, and then calculate its three-dimensional data according to the distribution and distortion of the patterns.
