Electronic medical record can greatly improve work efficiency of the hospital and medical quality in the clinical application. Meanwhile with the rapid development of virtual reality (VR) and augmented reality (AR) technology, people's life will adopt a new way. In this paper, Electronic medical record system (EMRS) based on augmented reality is proposed. The system consists of server, Android device...
Nowadays, the LED industry has witnessed an ever-growing development. LED intelligent lighting system, which is highly-efficient, environment-friendly, intelligent, and user-friendly, has become a new trend in the lighting industry. Formed by LED lamps, wireless sensor network needs a large amount of nodes. To realize its IP, a large number of IP addresses are needed. But the wireless sensor network...
A design scheme of wireless data transmission system is presented, which adopts Nuvoton N32926 embedded microprocessor as the system controller and RT-Thread embedded operation system is used. This paper describes the compiling and transplanting of TI CC3100 device driver, such that the system can send the data to CC3100 via the N32926 SPI interface. Finally, the description of how the system accomplishes...
With the modernizing lifestyle, more and more amusements and sports could be done indoor. The time people spend in indoor activities accounts for eighty percent. Air quality indoor has a great effect on human health. At present, widely used environmental monitoring equipment in the market is designed only to monitor environment, not support such appliances as humidifier and air purifier. Therefore,...
Human face detection plays an important role in applications such as secure access, video surveillance. In view of the poor detection rate and low speed of the detection for faces in profile view, pose varied and complex background, this paper proposes the KL-Gaussian Model algorithm in YCbCr color space for face detection, which is designed and implemented on the TMS320DM6437 platform. Furthermore,...
To enable multichannel audio streaming play simultaneously with one set of audio device in Digital Smart Home Terminal, multichannel data resampling and sound mixing should be realized. This paper introduces the resampling and mixing filter components based on the frame of Mediastreamer2. Sinc function interpolation method is used to realize implementing sound mixing technique in digital smart home...
This paper puts a skin color model which is based on YCbCr Gauss model and KL Transform carried on face detection. The region model and the simple Gauss model of the skin color are established in the KL color space and the YCbCr color space according to clustering. Skin regions are separated from non-skin regions by the optimal threshold which is obtained by an adaptive algorithm. Then the segmentation...
This paper introduces a proposal design of video surveillance system that bases on the mediastreamer2 library. It is launched directly from a web page by using ActiveX control. The benefit of using the control is to demonstrate via a web page that runs a GUI written in the dialog box architecture of MFC.
H.264 is well known as best video codec ever. And mediastreamer2 is an open-source software to make audio and video real-time streaming and processing. Written in pure C, it is based upon the ortp library. This paper presents the method of how to implement h.264 video streams transfer based on mediastreamer2. In the end we show the actual performance of our system.
As the widely application of digital multi-media technology, H.264 has become one of the most popular video standards for its better performance. This paper proposes optimization methods of the x264 decoder which is an implementation algorithm of H264 based on DaVinci Technology, especially including taking advantage of the DMA resource and cache optimization strategy in purpose for memory access...
Currently, the mediastreamer2 contains internal support for G.711u, G.711a, speex and gsm. However, it does not contain internal support for the popular G.729, which is known as the best audio codec ever. In this paper, we present the method of how to implement a G.729 codec filter on mediastreamer2. Then, we evaluate the performance of the G.729 filter in our platform. The experimental results show...
As the widely application of digital multi-media technology, G.729 has become one of the most popular audio standards. In this paper, the TMS320DM6446 which is a Davinci-based multi-core processor is chosen as our platform. We present our implementation method of G.729 algorithm which is compatible with eXpress DSP algorithm interface standard - digital media (xDAIS-DM, also called "xDM")...
