Package boofcv.core.encoding

Class ConvertNV21

java.lang.Object
boofcv.core.encoding.ConvertNV21
public class ConvertNV21 extends 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.
