What is dog nose print detection?

As long as it involves identification, whether it is humans or pets, it needs to be based on unique and indelible characteristics, such as our fingerprints. If this requirement is placed on cats and dogs, nose prints are very similar features.

Nose prints, like fingerprints, are also unique and very stable. As long as you compare the photos of pets when they are young and grown up, you will find that if there are no external factors, the lines on the nose will continue on the pet's life in the same pattern, and even the smallest details will not change. . Moreover, nose prints are unique and are the most representative personality traits of pet dogs.

Nose print technology is a very mature identification solution. As early as the 1930s, Canada began to print nose prints for dogs to identify different individuals. Nowadays, with the advancement of AI technology, computers have been able to automatically record and match, and then calculate and analyze the results, finally realizing the electronic process of nose print recognition. As long as the dog owner takes a photo of the dog, the computer software can automatically locate the nose print and record it into the computer database, becoming the dog's own "ID card."

Recently, Changsha, Hunan Province announced that with the help of a dog’s nose print photo, you can easily apply for a dog ownership certificate online. In the near future, the dog owner will be able to insure the dog. If the dog accidentally gets lost, Nose print data can also be used as evidence for dog hunting.

The principle of nose print recognition is actually very simple. Like face recognition, nose print recognition also collects image information, and then through data processing, extracts the key data and features, and compares it with the massive data stored in the database. Yes, finally finding out the unique identity.

Their shortcomings are even the same. The difficulty of face recognition lies in the processing algorithm of face data under various lights. To become an excellent face recognition software, one thing that needs to be achieved is that it can obtain data on key points regardless of the light. The same is true for nose print recognition. Maybe it cannot respond particularly sensitively when the light is dim, but as long as the light angle is adjusted, there is no need to worry about the accuracy of the data.

With the rapid development of science and technology, different biometric identification technologies are constantly iterating, which has brought great changes to our society. In the future, after being applied to all dogs, pet management in cities will also have some good effects. As long as the nose print recognition technology is available, if the dog is abandoned, the competent authorities can quickly find the owner through the electronic system and give him the appropriate punishment. Officers will not have to worry about finding lost dogs. The electronic dog files will send the dogs home very quickly.
