What is the importance of living body detection technology in face recognition ?

In actual application of face recognition technology, in order to improve the security of the application and prevent others from using props to attack face recognition, the face recognition technology and the living body detection technology will be used in combination, and the user is more at ease when using it. So, what is the importance of living body detection technology in face recognition? What is a biopsy? Face biometric detection mainly judges whether the face is alive by recognizing physiological information on the living body, and the biometric detection technology can use the physiological information as a vital feature

The difference between Rolling Shutter and Global Shutter

What is a shutter? The shutter is the mechanism by which a camera controls the effective exposure time of a photographic film. It’s an important part of the camera. Its structure, form and function is an important factor to measure the level of the camera. Generally speaking, the wider the shutter speed range, the better. The low number of seconds is ideal for shooting moving objects, with one camera emphasizing that the shutter speed can be as fast as 1/16, 000 seconds, making it easy to catch a rapidly moving target.  But when you’re shooting a picture of heavy traffic at

What is a starlight camera?

In terms of camera function classification, starlight level camera is a kind of low illumination camera. Low illumination camera is a camera that can take a clear image under low illumination conditions. According to minimum illumination to judge the disadvantage and advantage for low illumination camera. However, since there is no unified international standard for management, each large image sensor manufacturer has its own measurement standard. The starlight camera is a level of low-illumination camera, which is usually classified as below: 0.1Lux: Dark light level 0.01Lux: Moonlight class 0.001Lux and below: Starlight Therefore, a star-level camera refers to a camera

What Is An Industrial Endoscope?

What is an industrial endoscope? Let our expert answer for you. Endoscopes are also called hole detectors.Its primary function is to explore the depth of the curved pipe and other places that can be observed but cannot be looked directly.It can observe its internal structure and condition in the sealed cavity, to realize not only long-distance observation but also close-range operation. All in all, endoscopic is a method for quality inspection and visual inspection of areas where human vision cannot be directly observed. The areas that cannot be found by human perception like containers, roller belts, non-removable equipment interiors, and

Do You Know What Is Camera ?

1. What is Camera ? Camera , we also call pc camera, computer eye, etc. As a video input device, it has been widely used in video conferencing, telemedicine and real-time monitoring in the past. In recent years, dure to with the development of Internet technology, the continuous improvement of network speed, coupled with the maturity of photosensitive imaging device technology and large-scale use in the manufacture of cameras, this has reduced its price to a level that ordinary people can afford. More and more people can also talk and communicate with each other on the network through the camera

What is face recognition, direct sunlight shooting and backlight shooting, side light shooting?

Face recognition The principle of the camera and the camera module is the same: the light is concentrated on the sensor through the lens to get a brightly colored and clear picture. However, when we shoot in the direction of the sun for a long time, the sun shines unreservedly on the lens.  Thus concentrating strong light on the fragile sensor, harming the camera sensor. I remember that some time ago, during the solar eclipse, according to reports that many photographers‘cameras burned out because they photographed at the sun for a long time and do not take any protective measures.
