ایری How to operate the presence of face recognition
With the ever-increasing advancements of the world of work, many businesses seek to use the invention of new technology to improve efficiency, improve performance and increase Safety and security of your workplace. Facial recognition is increasingly popular, especially in attendance monitoring and employee management.
انی Face Biometric Technology
Biometric technology by examining parameters that are biologically present in people and are completely unique; It works like every person's face.
The concept of face recognition dates back to the 1970s, which led to the recognition of faces by computers. This technology is becoming more powerful and accurate day by day, and it is considered a leap in the world of technology, which has gained a lot of popularity due to the ease of identification and very low error rate.
ان Face Identification Process in the presence and absence
In general, the face recognition process is such that digital images of faces are taken and with information data (images of employees) which we have already collected, is compared in the system; After matching, the system announces the answer.
Face recognition is one of the most important and advanced technologies in artificial intelligence, by which people's faces can be recognized in images and videos. and distinguished them from each other. Facial recognition has many uses and benefits from many advantages, such as: the possibility of accurately identifying people with high accuracy, which can be used in security systems to protect resources and investigate and detect unusual behaviors in images and videos.
ان Face Detection Processes in the presence and absence
1- Capturing the initial images of the face of the people
The initial images of the employees are given to the device at this stage.
2- Face analytics and scrutiny
After inputting the initial image, the facial recognition system analyzes the facial image, draws the facial geometry and facial expressions, and Reads. Face recognition technology usually looks for the following: the distance between the eyes / the distance from the forehead to the chin / the distance between the nose and the mouth / the depth of the eye socket / the shape of the cheekbones / the contour of the lips, ears and chin
3- Save the imagination into the form of computer data
This system converts the face recognition data into a string of numbers or dots called face print. Each person has a unique facial expression. The information used by facial recognition can also be used in reverse for the digital reconstruction of people's faces.
4- Face matching with stored data
Every time the personnel stand in front of the device, the device starts to process and compare the person's face with the stored data and in In the form of confirmation of compliance, an entry or spending permit is given, or traffic is recorded.
🔷🔸مواردی که هنگام ثبت چهره باید به آن توجه کنید
Clear face view, complete with front view and high resolution
The best way to increase the accuracy of this system in storing basic face information in the database is to use the "acquaintance phase" which includes taking several photos of the same person under different environmental variables, such as daylight, night light, indoors, during It is motion and stillness.
Detailed data for comparison
Each subsequent image taken is then compared with database information to confirm that both images are of the same person.
ایری Sensor Types of Face Identification
Facial recognition devices are based on infrared technology or visible light technology.
ان Face Detection with Infrared Sensor
The use of infrared has been common in electronic devices for years due to its low cost and low battery consumption. Various attendance and absence systems also mainly use infrared. However, the use of infrared technology faces many limitations. For example, in the conditions of dust, smoke and intense sunlight, the performance of devices based on this technology will be disrupted.
