Two Anti-aliasing Methods for Creating a Uniform Look

Context. In the pursuit to render at good quality, anti-aliasing will be needed to reduce jagged edges. A challenge is presented where the image to be rendered consists of different elements like GUI and background. One anti-aliasing method alone might not be able to handle this due to some anti-aliasing methods not being applicable to certain elements within a rendering. Combining two different anti-aliasing methods on different elements within a rendering can however make parts appear extra blurry in relation to the rest, as some methods are prone to creating unwanted blur at specific occasions.
Objectives. This thesis' goal is to present a method for applying anti-aliasing to an image containing different elements, while managing to render it with good quality and keeping a uniform look.
Method. An experiment presented in the form of a user study was conducted for finding a suitable method for creating a uniform look. 26 respondents participated in the experiment, where they would rate a number of images by how uniform each were perceived as.
Results. The results from a user study did not meet the author's predictions, where it was expected that FXAA would help create a uniform look when applied last as a final post-processing effect. However the respondents of the user study had varied opinions, as the results showed that all three methods presented in the experiment all were perceived to display a uniform look.
Conclusions. A conclusion could be drawn that either anti-aliasing can not affect images greatly enough for the result to be perceived as non-uniform, at least for the two anti-aliasing methods which were tested. Or that the material presented in the survey did not manage to present an articulate display for the respondents.
