Regarding Luma & Chroma Relation in 4:2:0 Images - venkata sunil - Oct 5 1:54:00 2005
Hi All,
Actually i am implementing some of the Picture
Effects.. like ZoomIn and ZoomOut. My input images are
in 4:2:0 YUV format.
As per as my Knowledge,
the luma, chroma relation in 4:2:0 format is like
this:
Luma Chroma
0, 1 --- Lines correspond to 0- line of chroma.
2, 3 --- Lines correspond to 1- line of chroma.
But i would like to know about the chroma
corresponding to 0-line in Luma... or 2-line in Luma.
Means, what is the exact chroma for each of luma line.
I will be so thankful if some one gives me the
solution for this.
With Thanks,
Sunil.
