![]() The method we’ll be covering here today relies on computing the Fast Fourier Transform of the image. If you could control your lighting conditions, environment, and image capturing process, it worked quite well - but if not, you would obtain mixed results, to say the least. ![]() The downside is that the Laplacian method required significant manual tuning to define the “threshold” at which an image was considered blurry or not. Could be implemented in only a single line of code.Relied on computing the variance of the Laplacian operator.Today’s tutorial is an extension of my previous blog post on Blur Detection with OpenCV.
