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 (Chapter, 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 ... -
Objective evaluation of relighting models on translucent materials from multispectral RTI images
Kitanovski, Vlado; Hardeberg, Jon Yngve (Peer reviewed; Journal article, 2021)In this paper, we evaluate the quality of reconstruction i.e. relighting from images obtained by a newly developed multispectral reflectance transformation imaging (MS-RTI) system. The captured MS-RTI images are of objects ... -
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 ... -
Quality Assessment of 2.5D Prints Using 2D Image Quality Metrics
Kadyrova, Altynay; Kitanovski, Vlado; Pedersen, Marius (Peer reviewed; Journal article, 2021)Quality assessment is an important aspect in a variety of application areas. In this work, the objective quality assessment of 2.5D prints was performed. The work is done on camera captures under both diffuse (single-shot) ... -
Reflectance estimation from snapshot multispectral images captured under unknown illumination
Kitanovski, Vlado; Thomas, Jean Baptiste; Hardeberg, Jon Yngve (Peer reviewed; Journal article, 2021)Multispectral images contain more spectral information of the scene objects compared to color images. The captured information of the scene reflectance is affected by several capture conditions, of which the scene illuminant ... -
A study on attributes for 2.5D print quality assessment
Kadyrova, Altynay; Kitanovski, Vlado; Pedersen, Marius (Chapter, 2020)Quality assessment is performed through the use of variety of quality attributes. It is crucial to identify relevant attributes for quality assessment. We focus on 2.5D print quality assessment and its quality attributes. ... -
Using watermark visibility measurements to select an optimized pair of spot colors for use in a binary watermark
Reed, Alastair; Kitanovski, Vlado; Falkenstern, Kristyn; Pedersen, Marius (Peer reviewed; Journal article, 2020)Spot colors are widely used in the food packaging industry. We wish to add a watermark signal within a spot color that is readable by a Point Of Sale (POS) barcode scanner which typically has red illumination. Some spot ... -
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 ...
