• Data Hiding by White Modulation in Color Direct Binary Search Halftones 

      Kitanovski, Vlado; Eschbach, Reiner; Pedersen, Marius; Hardeberg, Jon Yngve (Journal article; Peer reviewed, 2017)
      In this article, the authors propose a method for hiding a visual watermark in color printed images with arbitrary, natural content. The embedded watermark is imperceptible under normal illumination, but it is revealed ...
    • Detection of Orientation-Modulation Embedded Data in Color Printed Natural Images 

      Kitanovski, Vlado; Pedersen, Marius (Journal article; Peer reviewed, 2018)
      This article addresses methods for detection of orientation-modulation data embedded in color dispersed-dot-halftone images. Several state-of-the-art methods for detection of orientation-embedded data in printed halftone ...
    • Halftone Modulation for Embedding UV Watermarks in Color Printed Images 

      Kitanovski, Vlado; Pedersen, Marius (Conference object; Peer reviewed, 2019)
      A method for embedding ultraviolet (UV) responsive watermarks in CMY printed halftone images, named white modulation (WM), was proposed recently, which is based on the iterative color direct binary search (CDBS) halftoning ...
    • Halftone modulations for data hiding in color printed images 

      Kitanovski, Vlado (Doctoral theses at NTNU;2019:8, Doctoral thesis, 2019)
      Techniques for embedding imperceptible data in printed images have been studied for the past few decades. The hidden data in printed images can be used to bridge the gap between printed media and the digital world in ...
    • Impact of printing surfaces with UV-curable inks on sound absorption 

      Kitanovski, Vlado; Nersveen, Jonny; Strand, Anton; Pedersen, Marius (Peer reviewed; Journal article, 2020)
      The recent UV-curable inks, used in modern inkjet printing systems, bring several advantages and therefore a potential to expand to new applications, including décor printing. In this work, we investigate the impact of ...
    • Masking in chrominance channels of natural images — Data, analysis, and prediction 

      Kitanovski, Vlado; Pedersen, Marius (Chapter, 2017)
      This paper addresses the visual masking that occurs in the chrominance channels of natural images. We present results from a psychophysical experiment designed to obtain local thresholds of just noticeable log-Gabor ...
    • Measurement of CIELAB spatio-chromatic contrast sensitivity in different spatial and chromatic directions 

      Kitanovski, Vlado; Reed, Alastair; Falkenstern, Kristyn; Pedersen, Marius (Journal article, 2019)
      This paper presents data on CIELAB chromatic contrast sensitivity collected in a psychophysical experiment. To complement previously published data in the low-frequency range, we selected five spatial frequencies in the ...
    • Orientation Modulation for Data Hiding in Chrominance Channels of Direct Binary Search Halftone Prints 

      Kitanovski, Vlado; Pedersen, Marius (Journal article; Peer reviewed, 2016)
      In this article, we propose a joint halftoning and data hiding technique for color images. To ensure high quality of the printed image, the color direct binary search (CDBS) iterative halftoning algorithm is used. The ...
    • UV Watermarking of Images in Clustered Dot Scenarios 

      Kitanovski, Vlado; Eschbach, Reiner; Pedersen, Marius; Hardeberg, Jon Yngve (Journal article; Peer reviewed, 2018)
      Digital Watermarking of printed images is an important capability for many applications. Visually detecting the watermark through, e.g. UV illumination, enables the watermark use in uncontrolled environments. In our previous ...
