Make the live broadcast source code more perfect by using Beauty SDK technology
Recently, the continuous financing of the live broadcast industry has made the vitality of the whole industry rise again. For the better and faster development of the industry, technicians in the industry have launched a new round of research on the live source code! By adding Beauty SDK to LVB source code as a concrete demonstration of the vitality of the LVB industry, let's take a look at how the LVB source code, as a cornerstone, is loved by the majority of users after joining Beauty SDK.
1) the first is the upgrade of audio acquisition.
Audio data can not only be combined with images to form audio and video data, but also can be collected and played in a pure audio way, which plays a very important role in many mature application scenarios, such as online radio and voice radio. The audio acquisition process is mainly through the equipment to collect the analog signals in the environment into the original data encoded by PCM, and then encode and compress the data into MP3 format and distribute them, so that both live broadcast system software and short video development software can make good use of this technology to achieve brand-new audio and video effects.
2), the second is the effect of beauty SDK treatment.
It is said that "80% of anchors cannot watch without beauty", and beauty filter is one of the most common features in live streaming products. Meitu's main products, which are going to be listed in Hong Kong recently, are Beauty cameras and Beauty Photos. Some media joked that they will have an impact on the cosmetics industry, in fact, thanks to the effect of Beauty SDK, so that beauty anchors can broadcast live confidently without makeup, while users of Beauty cameras can shoot "better themselves."
The main principle of Beauty SDK is to achieve the overall beauty effect through "skin grinding + whitening". The technical term of skin grinding is "denoising", that is, the noise in the image is removed or blurred. The common denoising algorithms are mean blur, Gaussian blur and median filtering. Of course, because each part of the face is different, the freckles on the face may show the appearance of eye black spots, so there is no need to remove the eyes when denoising the whole image. therefore, this link also involves face recognition and skin detection technology.
3). The effect of joint broadcasting with Beauty SDK
Joint broadcasting is a common requirement in ILVB. The implementation of Beauty SDK technology enables real-time interaction between VJs and some viewers, realizing the effects of dynamic stickers, beauty filters and video beautification, and then playing the interactive results to other viewers in real time.
The new image processing and beautification software development kit based on face recognition technology integrates beauty filters, 2D and 3D dynamic stickers, video beautification and other functions. We provide basic application SDK integration access, SDK function customization, cloud API call, face recognition technical support and other services.
