  • Adaptive watermarking – two ways to define it 
    RADULESCU, Monica; IONESCU, Felicia; STOICA, Cristina; STOICA, Valentin (Technical University of Moldova, 2005)
    Digital watermarking has been proposed as a solution to the problem of copyright protection of multimedia data in a networked environment. It makes possible to tightly associate to a digital document a code allowing the ...
  • Aspects of image transmission on the governemental communications systems 
    RĂCUCIU, Ciprian; DOCHIŢOIU, Constantin; JULA, Nicolae; PEARSICĂ, Marian (Technical University of Moldova, 2005)
    Data security became a very important problem in our days. For this reason the algorithms involved get faster and more resistant to cryptographic attacks. Because of the improvement of the channels, images are more often ...
  • A fast vector quantization image encoding using Tchebichef moments 
    BELDIANU, Spiridon Florin (Technical University of Moldova, 2005)
    The codeword searching sequence is sometimes vital to the efficiency of a VQ encoding algorithm. In this paper, we present a fast encoding algorithm for vector quantization that uses Tchebichef moments of an image block ...
  • Objects of high orders in restoration of images 
    МАRDARE, Igor (Technical University of Moldova, 2005)
    This paper deals with the process of transformation of groups of defective objects in order to restore their true images. The processors created on basis of objects of higher order in comparison to restored ones, appear ...
  • Processor on basis of associative memory in restoration of images 
    МАRDARE, Igor (Technical University of Moldova, 2005)
    Field of researches is the process of revealing of homomorphous displays between objects. Such functions are capable to carry out the suggested 3-rd order objects. By its nature search of associative objects is isomorphic ...
  • The system for obtaining three-dimensional images 
    GÎSCĂ, Vasile; OBADA, Gheorghe (Technical University of Moldova, 2005)
    The current article contains the description of a system for obtaining 3D (stereoscopic) images by means of a lenticular raster. This system consists of the following components: a digital photo camera or a scanner, a ...
