Hi TI experts,
I have some questions about NF block concept and tuning.
1. 2 LUTs, Combined LUT and Division LUT are used for NF tuning. Could you help provide examples of these 2 LUTs?
2. I can find 'coeff.txt' in 'psdk_rtos_auto_j7_06_02_00_21\pdk\packages\ti\drv\vhwa\examples\vhwa_nf_test' folder. Could you help explain what it is used for?
3. Concept. According to the formula, I think the basic concept of NF is that 1-D Gauss filter and weighted with intensity difference, which is assumed follow Gauss distribution. Please correct me if I was wrong.
4. Sigma-s and Sigma-c. There are not registers for these 2 parameters. I think I can adjust either or both to generate LUTs then check output image, correct?
Best regards,
Zhishen
