I need to rotate a video stream of 1920 * 1080 image by +/-15 degrees. I'm using Altera FPGA (probably ARRIA 10, but didn't choose specific component yet).
I want to do it using LUT's, but I can't seem to find any useful info on the internet regarding that method.
Can someone explain what is the main idea and how do I rotate?
thanks.
 

I assume you'll have some form of external image buffer. You normally write into the buffer normally then read out with the rotation. The lut would generate the address sequence needed to perform the rotation.

Thanks for your answer.
I'm guessing by external buffer you mean DDR. What do you mean by 'read out with the rotation'?
The lut would hold which info? what does it mean the address sequence..?
