displayed on the computer is different from the color printed. The main algorithm of JAVACV is to compute the color of pixels, and to obtain the similarity degree by various mathematical transformations. I personally think that this way is too far-fetched, or to work on the vector map, because all the images in the brain are vector. (Personal opinion, don't spray, Cherubim) (ii) Awareness of video Video co

I used qt4 + mplayer to use a player. It seems like adding a shell is boring. My classmates also told me that mplayer is not so easy to do. I still remember this sentence until now. At that time, we learned linux together and felt that it was good to use qt for secondary development. Till now, I have been familiar with ffmpeg, sdl, OSS, and OpenGL. I realized that it was so interesting to develop a player. Here, I want to sort out my ideas, because I have encountered many problems. General proc

Computer audio, video type of fault is a lot of users will encounter in the use of computers, when the phenomenon of such failures, there are many solutions. There are mainly the following types: 1. First check whether the speakers are normal, you can connect the speakers on other sound sources, such as MP3, detect sound output is normal. 2. Check is not due to the installation of the appropriate p

the sampling frequency is the sampling period or the sampling time, which is the time interval between the samples. The popular speaking sampling frequency is refers to the computer each second gathers how many sound samples, is describes the sound file the quality, the tone, the measurement sound card, the sound document standard. In today's mainstream acquisition card, sampling frequency is generally divided into 22.05KHz, 44.1KHz, 48KHz three levels, 22.05KHZ can only achieve FM broadcast so

Change the network location of a user's computer Windows Media Player, a free player from Microsoft, is a component of Microsoft Windows, often referred to as "WMP," to support enhanced functionality through plugins. Starting with Win7, Windows Media Player 12 introduced the play to feature, but this feature can also be win8/win8.1 in Windows Media Player 12 for continuation and hardening. Now let's explore the support of new and old platforms such as win7/win8/8.1, how can a wireless

speed, the requirements will be very high. So now the video is basically compressed video. For example, there is a very long lens that is a person talking. Obviously, most of his body is not moving, only the mouth of the piece moved. The compression process retains the fixed pixels and makes the pixel changes in the mouth part. So the video is not just a f

If you need to access images, audios, and videos of different encoding formats in your work, you are likely to be using multiple tools to convert these diverse media formats. It would be great if there is a multi-in-one conversion tool that can process all image/audio/video formats. FormatJunkie is such a multi-in-one media conversion tool, which has an extremely friendly user interface. Even better, it is

applicability. It is interconnected across platforms and supports complex network environments. Both 2g, 3G, and satellite and broadband can achieve communication. You can open audio and video applications anytime, anywhere. Whether you are using a computer, mobile phone, or iPad, it doesn't matter whether you download and install the client. The compatibility of multiple platforms has brought us a boom in
