Binarization of Matrix Codes

Part of the Lecture Notes in Computer Science book series (LNCS, volume 2766)


In this chapter, the binarization of matrix codes is investigated as an application of supervised learning of image processing tasks using a recurrent version of the Neural Abstraction Pyramid.

The desired network output is computed using an adaptive thresholding method for images of high contrast. The network is trained to iteratively produce it even when the contrast is lowered and typical noise is added to the input.
