    Technical description: Image recognition is a computer technology for image processing, analysis, and understanding, in order to identify the target of various modes.

Recognition process includes image preprocessing, image segmentation, feature extraction and matching judgment. In simple terms, image recognition is how the computer read the contents of the picture like people. With the image recognition technology, we cannot only acquire information faster through pictures searching, can also produce a new way to interact with the outside world, and even make the outside world operated more intelligently. Image recognition includes bar code identification, face recognition, fingerprint recognition, dynamic object recognition in intelligent transportation and so on. Image recognition technology is equivalent to an extension of the human visual perception, belonging to an important area of artificial intelligence. With the rapid development of computer and information science and technology, image recognition technology has gradually become a basic technology of artificial intelligence. Its relevant technical fields are increasingly wide, and the application has become even more deeply. The VTAIR image recognition technology developed by Voicetune is mainly used in:

   1.      toys

2.         Robot (visual navigation)

3.         Intelligent Device (attendance machines, cameras, access control systems, etc.)

4.     The image searching (large database)

5.       Precision Instruments (engineering survey, accurate positioning)

6.         Medical (image processing)

7.        Military (sonar radar image processing)
