WebIn photography aliasing is a form of distortion that occurs when two elements of the signal being processed to form a digital image become indistinguishable from one another. Aliasing often appears in an … WebWhen data that makes up the image has a different resolution than its representation on the screen we will see aliasing effects. How noticeable these are depends on how much down-sampling takes place in the change of resolution (if any). When subsampling data, aliasing is reduced by smoothing first and then subsampling the smoothed data.
