RGB color Space1, three-color principle: Most of the colors can be red, green, blue three colors according to different proportions of the synthesis, the same vast majority of monochromatic light can also be decomposed into red and green blue three kinds of shadeThe red, green, and blue three colors are added by different proportions. Blending is called additive process color. Some of the process color laws are:Red + green = yellow;Green + blue = cyan

Original: WPF: Two ways to convert an HTML RGB color value to a color object(1) Mode one:Color Color1 = (color) System.Windows.Media.ColorConverter.ConvertFromString ("#E0E0E0");(2) mode two:Color Color2 = Converttocolor ("#E0E0E0");　　public static System.Windows.Media.Color Converttocolor (string value) { int r = 0, g = 0, b = 0; if (value. StartsWith ("#")) { int v = convert.toint32 (value). Substring (1), (+);

representedIn plain alpha_8, Alpha is made up of 8 bits.The argb_4444 is made up of 4 4-bit, or 16-bit,The argb_8888 is made up of 4 8-bit, or 32-bit,Rgb_565 is R is 5 bits, G is 6 bits, B is 5 bits total 16 bitsThus:Alpha_8 represents a 8-bit alpha bitmapargb_4444 represents a 16-bit ARGB bitmapargb_8888 represents a 32-bit ARGB bitmaprgb_565 represents a 8-bit RGB bitmapThe higher the number of bitmap bits, the more color information they can store

Problem description: when using GPU for image processing acceleration, the image format is generally RGB 3-channel images, each occupying one byte, that is, 24-bit pixel images. When Cuda accesses data elements, if each thread accesses 8-bit, 16-bit, 32-bit, and 64-bit, the corresponding data segment length can be 32 bytes, 64 bytes, 128 bytes, and 128 bytes, It can meet the requirements of global memory combined access and improve the global memory

Zhang happy Windows 10 IoT Development Notes: use the software PWM in Lightning to drive RGB LEDs, iotpwm It seems that Windows 10 IoT has never been used up again. So, let's write a blog about the story. In fact, I wanted to write it about half a year ago. At that time, I wanted to build a Windows 10 IoT-based car, but Raspberry Pi native didn't support PWM. Baidu also couldn't find it, and went around GitHub, and found Lightning at @ ms-iot, and the

In the beginning, we want to get the corresponding scene depth map from the original image sequence, the problem is as follows: (1) How the RGB image is converted into a scene depth map. First, we need to have a clear concept: only from a single RGB image, the depth of information is not available. The grayscale value of each pixel of the depth image can be used to characterize a point in the scene from

The following is the yuv420 to rgb24 function. You have tried this function. The parameters are as follows:Src0 is the starting pointer of the Y volume, src1 is the starting pointer of the U volume, and src2 is the starting pointer of the v volume.Dst_ori is the starting pointer of the RGB buffer.Width is width, height is high The YUV volume distribution for data in yuv420 format isY is the starting pointer of data.The U volume is the starting pointer
