After the face recognition system was formally used at the opening ceremony of the Beijing Olympics, the face recognition technology has received extensive attention in the country and has been promoted in applications such as access control and attendance.
Face Recognition Technology Overview Face recognition is based on human facial features. For the input face image or video stream, first identify the characteristics of each part of the face, the position information of each major facial organ, and based on these information, further extraction Biometrics contained in human faces are compared with stored face templates to identify people.
Facial recognition algorithm is widely used in face recognition technology. It integrates computer image processing technology and biostatistics principles. It uses computer image processing technology to extract portrait feature points from video and uses biometrics. The principle of learning is analyzed to establish a mathematical model, namely a face feature template. Using the established face feature template and the subject's face image for feature analysis, a similar value is given based on the results of the analysis. Through this value, it can be determined whether the same person.
What are the characteristics of light steel villas? Is it suitable for long-term use?
Light steel villas are very popular and fashionable. They are a kind of Prefabricated House. They are the Customizable Series Products of our company. In fact, they are mainly villas assembled with new materials. Moreover, it uses high-strength light steel keels for construction, which guarantees stability, and the construction cost is also very favorable, and the construction of the villa can be completed quickly. So what are the characteristics of this type of villa? Is it suitable for long-term use?
Strong shock resistance
Many people are more worried that such villas cannot resist earthquakes and are not safe enough. In fact, it adopts a light steel structure, the building is light in weight, and the metal materials can guarantee a long service life. As long as the design is reasonable and the structure is stable, its seismic performance is also guaranteed.
Good windproof performance
The light steel villa adopts the mode of light steel keel and foundation installation, and expansion bolts, anti-pull parts, etc. are used in the middle, and the installation stability is also guaranteed. The wind resistance of this type of villa can reach 12 typhoons, and it can be used even in some cities with harsh environments.
good sound insulation
After all, the villa is still a residential area, no matter what type of material it is, it is necessary to determine its specific sound insulation effect. The sound insulation effect of the wall is good, and some materials for heat preservation and sound insulation can also be added to ensure good sound insulation effect. At the same time, the indoor living comfort is also very good.
good warmth retention
The heat preservation of light steel villas is good, because the villas are made of thermal insulation fiber cotton, maintenance panels, etc., and the thermal insulation performance is also good. Therefore, when building a villa, we must also pay attention to the specific conditions of its materials. High-quality materials that are thermally insulated and can ensure a long service life are our first choice.
Good environmental performance
The reason why light steel villas are now being used in many areas is mainly because they are cheap and have good environmental protection performance. Its materials can save a lot of wood, plastic steel, etc., and the construction is convenient, and the steel can be used repeatedly without causing environmental pollution.
