# vImage_ARGBToYpCbCrMatrix

The 3 x 3 matrix that the vImage library uses to convert from RGB to YpCbCr.

## Declaration

```swift
struct vImage_ARGBToYpCbCrMatrix
```

## Overview

Overview The vImage library uses this matrix to convert from RGB to YpCbCr using the following multiplication:         | Y' |   | R_Yp        G_Yp   B_Yp      |   | R |         | Cb | = | R_Cb        G_Cb   B_Cb_R_Cr | * | G |         | Cr |   | B_Cb_R_Cr   G_Cr   B_Cr      |   | B |
