monitoring on the Internet is generally based on Mjpeg-streamer.This approach leverages the underlying driver of the V4L2, and then works with streaming MJPEG this format, and then browses the video and controls through the browser.The following is implemented with a scheme that is closer to the real ip-camera.First look at the Netizen Sunkwei wrote "Webcam application based on V4L2, local pre-supervisor"http://blog.csdn.net/sunkwei/article/details/6

We are a GPS product based on WinCE, and customers need the camera function. Our product integrates the camera function of two solutions: USB camera and camera based on tvp5150 video codec (camera sensor, only the USB camera is introduced here.
To implement this function, we need to do the following work.
1. there should be many USB cameras that support wicne, and drivers should not be shared. Therefore, we need to select a USB camera based on project requirements (such as pixel requirements, w
In the known WIN8 development system, there are many different designs, such as the WP7 Metro UI, the built-in PDF reader that can read PDFs, the WebCam running on the browser, and the new built-in desktop split screen, and so on. However, because the current version of the WIN8 is also relatively primitive, the functions of the modules are not strong enough, so most of these features in file form scattered in the WIN8 system directory.

Before learning "signal and system", for the use of FFT () function analysis of discrete, continuous time signal spectrum out of the result has been a smattering of knowledge, this semester learned "digital signal processing", learning the discrete Fourier transform (DFT), the previous written procedures to do further understanding.
Before this, the CTFs, Dtfs, Ctft, DTFT for

Summary:Classification and Regression tree (CART) is an important machine learning algorithm that can be used to create a classification tree (classification trees) or to create a regression tree (Regression tree). This paper introduces the principle of cart used for discrete label classification decision and continuous feature regression. The decision tree creation process analyzes the information Chaos Measure Gini index, the special processing of c

According to formula (3), the PX parameter is a discrete value (although continuous PX can be obtained by an algorithm, we will introduce it later ). Therefore, the obtained distance value also changes. The degree of hop variation reflects the ranging resolution and accuracy.
If you rewrite formula (1) to X = FS/Q and perform the derivation based on Q, you can g
