Fast QR Code Detection in Arbitrarily Acquired Images
Luiz Belussi,Nina S. T. Hirata +1 more
TL;DR: This work employs Viola-Jones rapid object detection framework to address the problem of finding QR codes in arbitrarily acquired images and proposes a post-processing algorithm that aggregates the results of the first step and decides if the detected finder patterns are part of QR code symbols.
Journal ArticleDOI
Automatic Programming of Morphological Machines by PAC Learning
TL;DR: This work presents the central ideas of an approach based on the representation of transformations by collections of observed-ideal pairs of images and the estimation of suitable operators from these data based on statistical optimization or, equivalently, on a branch of Machine Learning Theory known as PAC Learning.
