In the literature, much research work has been done in the area of speaker verification. The developments include: different types of speaker verification techniques, methods for feature extraction, measures for telephone channel compensation, system robustness etc. In contrast, the problem of acoustic feature selection for speaker verification has been relatively neglected. Hence our aim is to...

Variations in offset print quality relate to numerous parameters of printing press and paper. To maintain a constant high print quality press operators need to assess, explore and monitor quality of prints. Today assessment is mainly done manually. This paper presents a novel system for assessing and predicting values of print quality attributes, where the adopted, random forests (RFs)-based, m...

Variations in offset print quality relate to numerous parameters of printing press and paper. To maintain constant quality of products, press operators need to assess, explore and monitor print quality. This paper presents a novel system for assessing and predicting values of print quality attributes, where the adopted, random forests (RF)-based, modeling approach also allows quantifying the in...

The effect of printer resolution and grayscale upon text print quality was evaluated both empirically and analytically. Empirical data on subjective print quality was obtained in two ways. First, people were asked to rate print quality on a scale of 1 to 10 where 10 was considered to be optimal. Second, people were presented with pairwise presentations of different print samples and asked to in...

Printability of paper is a multidimensional concept consisting of runnability and print quality. The lack of definition for print quality makes printability rather ambiguous. In this paper we discuss the measurability of the high-level printability and print quality and present an interpretation of the measurements of low-level print quality related characteristics as information channels about...

Image quality assessment is a difficult and complex task due to its subjectivity and dimensionality. Attempts have been made to make image quality assessment more objective, such as the introduction of image quality metrics. However, it has been proven difficult to create an image quality metric correlated with perceived overall image quality. Because of this, and to reduce the dimensionality, ...

Good print quality is the result of achieving high quality for a large number of attributes including color (color gamut and reproduction accuracy), density, tonal quality (tone reproduction and details in highlight, shadow and mid-tone), gloss, line quality (width, blurriness, raggedness,), text quality, adjacency (e.g. inter-color bleed), micro-uniformity (graininess), macro-uniformity (mottl...
