adopted by multiple electronic and electrical appliance manufacturers is to Convert RGB to YUV to maintain compatibility, and then switch back to the RGB format as needed, to display color images on computer monitors.
Rgb24 indicates that the R, G, and B components each occupy 8 digits.
Rgb32 indicates that the four components R, G, B, And a each occupy 8 digits.
When you edit the color in the appearance of Windows desktop properties, there are two ways to edit the color: YUV and RGB.

grayscale of images :The process of transforming color images into grayscale images becomes the grayscale processing of images. The color of each pixel in a color image is determined by the R, G, and b three components, and each component has a value of 255, so that a pixel can have a range of more than 16 million (255*255*255) color variations. and gray image is R, G, b three components of a special color image, the range of one pixel change is 255, so in the digital image processing species ge

H264 is a new generation of coding standards, high compression high-quality and support a variety of network streaming media transmission is known, in terms of coding, I understand his theoretical basis is: reference for a period of time, the statistical results show that in several adjacent images, there is generally a difference in pixels only 10% of the points, The difference in brightness does not change beyond 2%, and the chroma difference is onl
elements of the "light", so there is enough space between elements, elements and elements to ensure the recognition degree;
Longer text has better readability and is easier for users to digest.
The spacing between lines and the length of the text has a significant effect on readability, especially in the dark background.Therefore, the length of space, word spacing, line spacing needs to be carefully considered.
Dark color does not mean that it is purely black, and the effects of dif

The link between HSI and RGB color space can be attributed to the following:the HSI space separates the luminance components in the RGB space first, The chroma component is then parsed into hue and saturation, and the angular vector is used to refer to the tonal component.

ETC Texture Compression formatEricsson Texture Compression, an open standard supported by Khronos, is widely used in mobile platforms. It is a lossy algorithm designed for perceived quality, which is based on the human eye's response to changes in brightness above the chroma change. Similarly, DXT,ETC also compresses a 4x4 block of pixels into a 64-or 12
advantage of using Cximager compression is that the pixels are constant, the chroma loss is low, the sharpness is high, and the compression rate can be set freely; The disadvantage is that only 4 images (GIF, BMP, JPG, PNG) are supported. The higher the computer configuration, the faster the compression, the image will be damaged after compression, the software for those who do not demanding high-definition, but also want to save disk space friends.[

The human eye resembles an optical system, but it is not an optical system in the ordinary sense, but is also regulated by the nervous system. The human eye observation image can be used in the following aspects of the reaction and characteristics:(1) From the spatial frequency domain, the human eye is a low-pass linear system, the ability to distinguish the scenery is limited. Because the pupil has certain geometrical size and certain optical aberration, the visual cell has certain size, so the
