In this paper, we move for a while away from the very technical issues of shape descriptors definition and verification and we focus on the question how visualisation of the computed data affects the final result of a visual query. We are replacing a traditional, linear presentation of n most similar outputs to a set of graph-like and scatterplot b...

The interface presented combines query-by-sketch and query-by-image modes of interaction. It is designed to harmonise extraction of several basic shape descriptors with 2d haptic pointing.

Should any museum or scientifi c library consider itself as an information technology laboratory? This article explores the lives of several pioneering museum and library projects focused on digital image retrieval techniques (CBIR). The research aims to contribute critical evaluation of museum and information technology domain relations in the fi...

The study explores integration of the tech-provided CBIR solutions with the everyday cultural practice. The research focus on the end-user experience. It has been designed in order to discover categories and relationships that constitute the social evaluation of the visual search. The observation was limited to the small group of digital natives a...

In the following paper we present tagging of visual forms as a strategy which relates to the solutions developed by the creators of the Standard MPEG-7 and which can have significant importance for the integration of visual searching into the contemporary systems of communication. The proposition is based on the observation of contemporary cultural...

In this paper a new approach to image segmentation was discussed. A model based on a data mining algorithm set on a pixel level of an image was introduced and implemented to solve the task of identification of craquelure and retouch traces in digital images of artworks. Both craquelure and retouch identification are important steps in art restorati...

W przedstawianej rozprawie zbadano możliwości komputerowego przetwarzania i analizy obrazu, ze szczególnym uwzględnieniem metod identyfikacji uszkodzeń warstwy malarskiej. Jako główny wynik przedstawiono nie publikowaną dotąd metodę segmentacji siatki spękań z zastosowaniem techniki eksploracji danych na poziomie pikseli obrazu. The thesis int...

In the paper a new proposal of semi-automatic method of craquelure detection in old paintings is presented. It is well known, that craquelure pattern is a unique feature and its character gives a significant information about the overall condition of the work, progress and cause of its degradation and helps in dating as well as confirming the authe...

In this paper an attempt has been made to develop a decision tree classification based algorithm for craquelure identification in old paintings. Craquelure can be an important element in judging authenticity, artist's workshop as well as for monitoring the environmental influence on the condition of the painting. Systematic observation of craquelur...

In this paper an attempt has been made to apply data mining techniques to the task of separation and categorization features in digital images of artworks. Both craquelure separation and retouching identification are important steps in art restoration process. Since the main goal is to enable recognition of character and cause of damage, as well as...

The watershed transform is one of best known and widely used methods for image segmentation in mathematical morphology. Since the definition, deriving from geology and nature observation is quite intuitive and straightforward to implement; many fast and powerful algorithms for watershed transform have already been presented. However, there still oc...

The paper discusses two key concepts required for the use of Virtual Reality and 3D modelling as a research tool for the humanities: data transparency -what is the type and nature of the archaeological/historical/ethnographical material on which the 3D model is based, and reliability - how the user can scientifically analyse the model. In this arti...
