TDA4AH-Q1: LDC Errors

I have done another test using 1920*1280 Image. With the matlab set at same values. The results are still the same. 
Attaching the files here: 1920.zip

Your output view size is too large for your input view (output image goes out of input image boundary on all the 4 sides).
You should try smaller "s" values and pick a good one for your output view.

Oh thanks gang, That worked properly.

BTW, is that a wide angle lens?
I cannot tell how wide the angle is from "img_viss_0017.yuv".

Yeah this is 120 FOV lens I guess, must be around that range.

I also noticed that you chose bicubic in tuning tool which slows down LDC to 50% throughput.
Bi-linear is better for performance.

Oh Sure, I preferred it because of accuracy reason. Will test it both ways lets see.

Thanks for the confirmation!
That is what I am guessing, but the sideview of the truck does not show much reference for judging the distortion.

Please let me know if you have any further questions.
Otherwise, I will close the thread.

Yeah, I had the confusion as well, as the objects are at distance it was hard to see untill i put these cameras on the bench with nearby objects.

Yeah am all good on this one.

Hello, I have encountered the same problem as you. May I ask how you resolved it? Is it possible to adjust the value of s from 2 to 1? Is there any other operation required?

yes you can do that in matlab. It will solve the issue
