This paper gives a visit report from the baggage handling halls at Vienna International Airport together with texts about image processing applications at airports. The paper is the final written document for the excursion group in the course “Applications of Image Processing” at Vienna University of Technology. The foci in the technical texts are on illumination, configuration (environment), s...

self-affine maps were successfully used for edge detection, image segmentation, and contour extraction. they belong to the general category of patch-based methods. particularly, each self-affine map is defined by one pair of patches in the image domain. by minimizing the difference between these patches, the optimal translation vector of the self-affine map is obtained. almost all image process...

Ancient document Image processing is an important area attracting many researchers in the recent period. Binarization is the first step while cleaning the document for further processing. Based on the degradation of the original document, either global or local thresholding methods are preferred. Thresholding phenomenon is a simple and practical approach to identify the cluster of pixels that a...

The aim of this thesis is to develop a mobile reading device for blind and visually impaired people. The key innovation of the system consists in its ability to assist the user during the image capturing phase utilizing CV algorithms and methods. In addition to the challenge of designing and building the device this work is focused on the pre-processing of document images under hardware limitat...

gesture and motion recognition are needed for a variety of applications. the use of human hand motions as a natural interface tool has motivated researchers to conduct research in the modeling, analysis and recognition of various hand movements. in particular, human-computer intelligent interaction has been a focus of research in vision-based gesture recognition. in this work, we introduce a 3-...

In January 1993, the American Institute of Architects and the International Union of Architects announced the "Sustainable Community Solutions" ideas competition. This paper describes principles and concepts illustrated in an award winning design competition entry based in Los Osos, California. The focus of this entry is the transformation of a suburban bedroom community on the California coast...

Binarization plays an important role in document image processing, especially in degraded documents. For degraded document images, adaptive binarization methods often incorporate local information to determine the binarization threshold for each individual pixel in the document image. We propose a two-stage parameter-free window-based method to binarize the degraded document images. In the firs...

One of the complex documents in the real world is city maps. In these kinds of maps, text labels overlap by graphics with having a variety of fonts and styles in different orientations. Usually, text and graphic colour is not predefined due to various map publishers. In most city maps, text and graphic lines form a single connected component. Moreover, the common regions of text and graphic lin...

The collections of historical books are an important source of information, both for the history of previous periods and for the development of the cultural documentation itself. Although to date, there have been made several attempts of digitalization and electronic navigation, there is not an appropriate frame of optical process and analysis of the content of these collections, consequently a...
