rgb 128 128 128

Recently, the algorithm is a function that involves converting RGB to YUV data. This common error occurs: Unsigned char * vline = (New unsigned char [width + 2]); // + 1;// Uline [-1] = uline [width] = 128; // 16-bit binary representation of-1: 1111

RGB and (converted from RGB to YCbCr to RGB) are irreversible, which can be seen from the inverse operation of the matrix. Attached Matlab code: Clc,clear1_source1_imread('1.jpg '); % read original RGB image figure (1); subplot (1, 2, 1); imshow

Yuy2 is often used in TV systems and output formats of many cameras. during processing, we often need to convert it to RGB for processing. Here we will briefly introduce the Conversion Relationship Between yuy2 (YUV) and
