International Conference on Cognitive Infocommunications (CogInfoCom)
作者: Péter Kardos Kálmán Palágyi Department of Image Processing and Computer Graphics University of Szeged Szeged Hungary
One of the fundamental issues of human and computational cognitive psychology is pattern or shape recognition. Various applications in image processing and computer vision rely on skeleton-like shape features A possib... 详细信息

International Symposium on image and Signal processing and Analysis
作者: Norbert Hantos Péter Balázs Department of Image Processing and Computer Graphics University of Szeged Szeged Hungary
In this article we study the uniqueness of the reconstruction in a special class of 4-connected hv-convex images, using two projections and the so-called morphological skeleton. Generally, if just the two projections ... 详细信息

International Symposium on image and Signal processing and Analysis
作者: Péter Kardos Kaiman Palâgyi Department of Image Processing and Computer Graphics University of Szeged Szeged Hungary
There are three possible partitionings of the continuous plane into regular polygons that leads to triangular, square, and hexagonal grids. The topology of the square grid is fairly well-understood, but it cannot be s... 详细信息

International Conference on Cognitive Infocommunications (CogInfoCom)
作者: Marianna Zichar Department of Computer Graphics and Image Processing University of Debrecen Debrecen Hungary
Traditional paper maps display information following the well-known rules based on experiences gathered during centuries. Nowadays, more and more geospatial information is represented in digital form and we have to fa... 详细信息

The reconstruction of hv-convex binary matrices (or equivalently, binary images) from their horizontal and vertical projections is proved to be NP-hard. In this paper we take a closer look at the difficulty of the pro... 详细信息

IEEE Canadian Conference on Electrical and computer Engineering
作者: Saif alZahir Faramarz Kashanchi Image Processing and Graphics Lab Computer Science Department UNBC
Measuring image quality is an interesting and challenging area of research. In this paper we investigate the performance of the statistical functions called copula as image quality measures. These functions are popula... 详细信息

15th International Workshop on Combinatorial image Analysis, IWCIA 2012
作者: Kardos, Péter Palágyi, Kálmán Department of Image Processing and Computer Graphics University of Szeged Hungary
Thinning is a frequently used strategy to produce skeleton-like shape features of binary objects. One of the main problems of parallel thinning is to ensure topology preservation. Solutions to this problem have been a... 详细信息

IASTED International Conference on Signal processing, Pattern Recognition and Applications, SPPRA 2012
作者: Kardos, Péter Palágyi, Kálmán Department of Image Processing and Computer Graphics University of Szeged Szeged Hungary
Thinning as a layer-by-layer reduction is a frequently used technique for skeletonization. Sequential thinning algorithms usually suffer from the drawback of being order-dependent, i.e., their results depend on the vi... 详细信息

IASTED International Conference on Visualization, Imaging and image processing, VIIP 2012
作者: Wahedul Islam, Md. Alzahir, Saif Computer Science Department Image Processing and Graphics Lab UNBC BC Canada
In this paper, we present an image watermarking scheme based on discrete wavelet transform and singular value decomposition (SVD) for color images. This scheme embeds the watermark into the luminance (Y) channel of YC... 详细信息

作者: Hantos, Norbert Balázs, Péter Palágyi, Kálmán Department of Image Processing and Computer Graphics University of Szeged Árpád tér 2 H-6720 Szeged Hungary
In binary tomography, the goal is to reconstruct binary images from a small set of their projections. However, especially when only two projections are used, the task can be extremely underdetermined. In this paper, w... 详细信息
