Face recognition is no longer strange Pig face recognition to understand? 【full text】

Scientific and technological developments with advances in technology, "fingerprinting" has been unable to fully meet the desire of people to explore the "face recognition" gradually became one of a very hot topic in recent years. As the technology matures, both the iPhone and the domestic brand-name smart phones have taken full advantage of the "face recognition" function.

"Face recognition" also brings convenience to people in all aspects of life. For example, you can use the "face recognition" feature on your phone to make payments; for security reasons, you can also use "face recognition" to log in to your funds account.

In addition, “face recognition” also plays a very important role in helping the police detect various cases, such as identifying the person’s gender, age, etc. through the person’s face and communicating with the police’s existing people. Face database for comparative analysis, so as to track the thief, criminals and so on.

I believe many people still have the impression that "face recognition" is even used in public toilets. Xiao Bian once reported to everyone that in order to encourage everyone to save paper and avoid the waste of toilet paper, some public toilets in the Tiantan Park had launched the “face recognition toilet paper machine”. Visitors need to remove hats, glasses, and screens. After standing for a few seconds, the paper slowly exited under the machine.

From this it can be seen that "face recognition" has inadvertently appeared in every corner of life.

Recently, according to reports from Guangzhou Daily, it is understood that not only "face recognition" but also a fresh technology "pig face recognition" has emerged.

According to the Guangzhou Daily, each pig's eating preference, food intake, and health status are not the same, so if you want to keep them well, you must first be able to distinguish them.

In the past, some pig farmers often used ear tags, implanted chips, etc. to identify the pigs. Now, you only need to use a mobile phone to sweep the pig's face, you can know its number, parents, The strains and other information can also minimize the damage to the piglet's body.

This technique makes it easier to manage the pigs finely.

However, compared with "face recognition", "pig face recognition" still has many technical difficulties to overcome.

Dr. Chen Yaosheng, chief scientist of the National Hog Industry Technology System and professor at Sun Yat-Sen University, said that during the photo shoot, the pig may be very uncooperative. The process of collecting it may be more troublesome and it takes a lot of work. In addition, the pigs are very similar in appearance due to their multiple births. Due to the influence of the living environment, the face is stained and it is less easy to recognize.

According to reports, at present, the team that masters the pig face recognition technology has already settled in Guangzhou seed industry town, and its research results will be widely used in aquaculture management, food safety and other fields.
