Does 4:2:2 to 4:1:1 use any filter?

[vetroxl]

Hi I would really like an answer to this as I am chasing down a problem and I'm not sure if it's due to aliasing. Does theippiYCbCr422ToYCbCr411_8u_C2P3R function use any filter?

Thanks.

Hi Vetroxl,

do you see some aliasing? the function doesn't use filter in principle.

Could be the image width?

The value of the fields of the roiSize have certain limitations:

- its width should be multiple of 4 and cannot be less than 4 for operation on two-channel images;

- its width should be multiple of 4 and cannot be less than 4, and its height should be multiple of 2 and can not be less than 2 for three-plane to two-plane image conversion;

- both height and width should be multiple of 2 and cannot be less than 2 for operation on three-plane images.

Best Regards,
Ying

Hi Ying,

Thanks for the reply. It was actually my monitor. I was seeing aliasing on everything that had a run of black followed by a run of white. The monitor has been RMA'd.

thanks.
