boofcv.core.encoding.ConvertNV21

public class ConvertNV21
extends java.lang.Object

Used to convert NV21 image format used in Android into BoofCV standard image types. NV21 is an encoding of a YUV image [1] (more specifically YUV 4:2:0) where Y is encoded in the first block and UV are interlaced together. The UV planes are at 1/2 resolution.
