rgb to rca

Convert RGB color to 16 bit color [Suitable for beginners with game programming] I need to judge the colorkey when doing 16bit alpha blending. In my game engine, the colorkey is represented by Windows RGB color, in this case, we need to convert the RGB color to a 16-bit color. below is my practice.The RGB color is a DW

The common two-dimensional code is black and white, which naturally improves the recognition accuracy. Recently, the color QR code has also appeared, but all I have seen is more interesting. For example, the QR code application can put your profile picture in the QR code. A simple idea is: can we use each channel/component of RGB to store a QR code? If the recognition accuracy does not affect or has little impact, a color QR code can be stored three t

During the operation, the following message is displayed: convert the image to the RGB image mode before editing. how can this problem be converted? There is a good method below. when you try to operate it, you will be prompted: first convert the image to the RGB image mode and then edit it. how can we convert it? The following is a good method. you can try to operate the image. sometimes, a prompt is displ

Retrieve the main color value of the image based on the uploaded image, and then search for the image based on the color, the quantizeImage method of Imagick can easily obtain the average RGB values of images. many Image sites retrieve the main color values of images based on the images uploaded by users, then, search for related images by color. Previously, the image was scaled (or mosaic) according to the online method, then each pixel was traver

YCbCr color space is used in face detection, so the conversion of RGB and YCBCR color space is necessary. In the following formula, the values of the RGB and YCBCR components are in the range of 0-255.RGB Go to YCbCr:Float y= (COLOR.R * 0.256789 + color.g * 0.504129 + color.b * 0.097906) + 16.0;Float cb= (COLOR.R *-0.148223 + color.g * -0.290992 + color.b * 0.439

What is a grayscale map? Any color has red, green, blue three primary colors, if the original point of the color of RGB (R,G,B), then, we can use the following methods to convert it to grayscale: 1. Floating-point algorithm: gray=r*0.3+g*0.59+b*0.11 2. Integer method: gray= (r*30+g*59+b*11)/100 3. Shift Method: Gray = (r*76+g*151+b*28) >>8; 4. Average method: gray= (R+G+B)/3; 5. Green only: gray=g; After using either of these methods to obtain g

Ref: http://www.360doc.com/content/11/1008/17/1016783_154377024.shtml There are many conversion programs from YUV to RGB on the Internet, but they are basically calculated based on the CPU. There are some methods based on CPU computing, the most primitive must be the direct floating-point operation based on the conversion formula. To increase the speed, you can use the left and right Shifts operation to convert the floating-point operation into an int
