TDA4VL-Q1: LDC bilinear interpolation

Part Number: TDA4VL-Q1

Hi All,

We have a step in stereo algorithm where we are using bilinear interpolation, I see there is a block in LDC module which does bilinear interpolation. Is it possible to use bilinear interpolation module inside LDC module as standalone by bypassing the other blocks, If yes, is there any examples using (openvx/fvid2) for the same?

Thanks & Regards,

Krishna

Hi Krishna,

Well it alone cannot be used. You need to atleast use mapping functionality using LUT..

Hi Brijesh,

Thanks for the response. For Bilinear inter block its mentioned as 1 cycle/pix. Any estimate available on how much cycles/pix is required by backmapping and Perspective transform block?

Thanks & Regards,

Krishna

Hi Krishna,

That remains same even for backmapping and perspective transform.
