In modern color TV system, three-tube color camera or color CCD camera is usually used to take the image, and then the obtained color images are separated and corrected to get RGB, then the lumi

many factors that affect the perceived color of the human eye, the perfect color illusion, or the dress that messes with the Internet. The point is that the human eye can be manipulated very well relative to the color to be recognized.Quality is a form of lossy compression, whereas JPG uses another method: the color model . A color space represents a set of colors, and its color model represents how the mathematical formula indicates the color (RGB, four separations CMYK).The great thing about

What is a CSS Filter? CSS Filter is an extension subset of conventional CSS. It can make the application objects (text, images, HTML elements...) produce blur, transparency, edge light, and other effects similar to those in Photoshop. The rational use of the CSS Filter can reduce the number of images used by the web page to reduce the size of the web page. You can also directly modify the filter parameters in CSS or use js to dynamically modify the CSS Filter parameters, to quickly update the

In this case, you might want to add some transparency to some of these elements, and in fact no matter which layer you add transparency to is futile. Because at this time there are only two cases: outside the circle is covered by the background color, the background color transparent is a rectangular enlargement, rather than a circle. What we want is: the background color of the mask is transparent, and the enlarged im

Baidu Encyclopedia above the introductionYUV is mainly used to optimize the transmission of color video signal, so that it is backward compatible with old black and white. Compared with the RGB video signal transmission, its greatest advantage is that it takes only a very small bandwidth (RGB requires three separate video signals to transmit simultaneously). where "Y" is the luminance (luminance or luma), which is the grayscale value, and "U" and "V" are the

FFmpeg x264 Encoding Guide Encoding H.264 in FFMPEG The defaults for x264 in FFMPEG are currently significantly detrimental to the quality of the encoded video. this is due to the internal behaviour of FFMPEG with respect to codec defaults. depending on the rate control method used, a number of different switches need applying to bring the settings into line with the x264 command line interface defaults. these are generally OK settings as they have been suggested by the author (s ). the necessar

seen from three dimensions of r,g,b.1.1.2YUVThe importance of YUV color space is that its luminance signal y and chroma signal u, v are separated. If only the Y signal component does not have a U, v component, then the image represented here is a black-and-white grayscale image. Color TV using YUV space is precisely to use brightness signal y to solve the compatibility problem between color TV and black and white TV, so that black and white machine c
