### 14.11. Bayer Matrix

#### 14.11.1. Overview

图 17.364. Example for the Bayer Matrix filter

“Bayer Matrix” filter applied with Scale X, Y = 20

A grand-sounding name for a simple filter. Bayer matrix is related to ordered dithering, which is an image dithering algorithm used to display a continuous image on a display of smaller color depth. The algorithm reduces the number of colors by applying a threshold map known as Bayer matrix (Wikipedia). The present filter uses the Bayer matrix only to create a pattern.
