Deep Neural Networks (DNN) have achieved state-of-the-art results in a wide range of tasks, with the best results obtained with… Expand In this paper, a method to design regular (2, dc)- LDPC codes over GF(q) with both good waterfall and error floor properties is… Expand We present a novel technique for steganalysis of images that have been subjected to embedding by steganographic algorithms. The… Expand This paper proposes a new method to embed data in binary images, including scanned text, figures, and signatures. The method… Expand A sequential algorithm is presented for computing the exact Euclidean distance transform (DT) of a k-dimensional binary image in… Expand A new method is presented for adaptive document image binarization, where the page is considered as a collection of subcomponents… Expand Abstract In this paper we present new implementations for morphological binary image processing on a general-purpose computer… Expand Abstract Two border following algorithms are proposed for the topological analysis of digitized binary images. The first one… Expand Abstract Based on a two-component descriptor, a distance label for each point, it is shown that Euclidean distance maps can be… Expand Aspects of topology and geometry are used in analyzing continuous and discrete binary images in two dimensions. Several numerical… Expand
