Using image recognition search engines (such as Baidu Zhitu and Tencent Youtu) to identify personal photos will not reveal personal privacy? That is to say, will the picture be uploaded?

Will reveal personal privacy within a certain range. Pictures will also be uploaded.

Reason: The basic principle of image recognition is "perceptual hashing algorithm", which needs to capture your image information first, then generate a unique string according to the image information, and then match similar strings. In the process of crawling and matching, you have actually uploaded your personal information.

Image recognition refers to the technology of processing, analyzing and understanding images by computer to identify different patterns of targets and objects. It is a practical application of applying deep learning algorithm.

At present, image recognition technology is generally divided into face recognition and commodity recognition. Face recognition is mainly used in security inspection, identity verification and mobile payment. Commodity identification is mainly used in the process of commodity circulation, especially in unmanned retail fields such as unmanned shelves and intelligent retail cabinets?

The traditional image recognition process is divided into four steps: image acquisition → image preprocessing → feature extraction → image recognition. Cognex is the representative of image recognition software abroad, while Tuzhi and Poseidon technology are the representatives at home. In addition, it also refers to the technology of classifying remote sensing images in geography.
