Sep 27, 2017 at 18:05 comment added Alan Wolfe I'm surprised you can't get a ground truth due to a field of view setting. Can you excplain? Anyways, another idea that may or may not work out is to use the image you have as a super sampled ground truth image: shrink it down to like 1/4 size or smaller using good filtering to minimize aliasing. Next, take the source image and shrink it down to the same size using bad filtering that causes aliasing. next use your AA techniques and compare them against the ground truth you have. Another option that may work is to use a different image to test AA on, one you can get a ground truth for.

Sep 27, 2017 at 8:45 comment added Varun Vijaykumar Unfortunately in my case, there is no ground truth image available. We cannot get these images due to some issues related to Field of View of the images. Is there any other way we can use the results and do the comparisons against each other ?
