Title:

Image Formalization via Descriptive Image Algebras
Authors:

Vera Yashina and Igor Gurevich
Abstract: In the framework of the Descriptive approach to image analysis and understanding, the concept of Image Formalization Space (IFS) is introduced. The elements of IFS are the different image representation forms through which a raw image passes while it is transformed into a recognizable form, i.e., into an image model. The structure and the main objects of the IFS are characterized and discussed. A system of concepts and a formal apparatus of descriptive image models are introduced to state the main axioms constituting the conceptual foundation for image formalization in image analysis and recognition. The topology of IFS is given by descriptive image algebra defining operations on pixels and their configurations, on pixel values, and on image states constructed using these operations.

Image Mining for Infomobility
Authors:

Davide Moroni, Gabriele Pieri, Claudio Salvadori, Paolo Pagano, Matteo Petracca, Ovidio Salvetti, Christian Nastasi and Massimo Magrini
Abstract: The wide availability of embedded sensor platforms and low-cost camera sensors – together with the developments in wireless communication – make it now possible the conception of pervasive intelligent systems based on vision. Such systems may be understood as distributed and collaborative sensor networks, able to produce, aggregate and process images in order to mine the observed scene and communicate the relevant information found about it. In this paper, we investigate the peculiarities of visual sensor networks with respect to standard vision systems and we identify possible strategies to tackle the image mining problem. We argue that multi-node processing methods may be envisaged to decompose a complex task into a hierarchy of computationally simpler problems to be solved over the nodes of the network. We illustrate these ideas by describing an application of visual sensor network to infomobility.

Detection of iris in image by brightness gradient projections
Authors:

Ivan Matveev
Abstract: A method is proposed to detect a human iris location and size in digital image given some point lying inside the pupil. Method is based on construction of histogram projections of local brightness gradients and interrelating local maxima of these histograms as probable positions of pupil and iris borders. Method has low calculation cost.

On the Construction of Gestalt-Algebra Instances and a Measure for their Similarity

Authors:

Eckart Michaelsen and Eckart Michaelsen
Abstract: Four construction principles that compose more complicated perceptual gestalts from less complex ones are defined in detail: Mirror gestalts, lattice gestalts, rotational mandalas, and clusters, respectively. These can be encapsulated as constructions in a production system. Since any of the four constructions can work on any gestalt, a recursive and very expressive scheme is set up with many prospective applications in image mining. Of particular interest is such analysis for aerial and satellite images and for façade images of buildings.

Title:

An Image-based Framework for Intellectual Decision Making in Medical Research
Authors:

Ovidio Salvetti, Yulia Trusova and Sara Colantonio
Abstract: Medical decisional problems strongly rely on the analysis and inter-pretation of diagnostic images acquired by different investigation techniques. Information extraction and correlation from these are usually demanding tasks that can burden the routine work of clinicians. In this paper, an image-based framework is presented which is devoted to the automated extraction of knowl-edge and data from biomedical images used for intellectual decision making in clinical and medical research. An ontological approach is adopted for encoding different kind of knowledge required in problem solving. Modelling the pre-clinical stage of Parkinson's disease is presented as eligible case study.

Pattern Recognition Imaging for AFM measurements
Authors:

Mario D’Acunto, Ovidio Salvetti and Mario D'Acunto
Abstract: The focus of this paper is on an algorithm for distortion corrections for atomic force microscope (AFM) recorded images. AFM is a fundamental tool for the investigation of a wide range of mechanical properties due to the contact interaction between the AFM tip and the sample surface. When a sequence to AFM images correspondent to the same area are recorded, it is common to observe convolution of thermal drift with surface modifications due to the AFM tip stresses. The surface modifications are material properties and add knowledge to the response of the materials on nanoscale. As a consequence, a suitable de-convolution of the thermal drifts on the recorded images need to be developed. In this paper, we present a method for correcting thermal drifts where the original images are corrected using a low-order polynomial mapping function. The precision achieved and the fast computation time required make our method particularly useful for image analysis in a wide range of applications.

Authors:

Boris Zalesky, Alexander Nedzved, Sergey Ablameyko and Pavel Lukashevich
Abstract: Position of the spinal column and vertebrae on the CT images is the main feature for orientation position of the patient. In this paper we propose an algorithm for determining the position of the spinal column and vertebrae. The algorithm consists of two parts: the definition of the spinal column and vertebrae with the ribs and the positioning of the body of the patient on the CT image.

Usage of Positional Representations in Tasks of Revealing Logical Regularities
Authors:

Alexander Vinogradov, Yury Laptin and Yury Zhuravlev
Abstract: A new approach to the problem of description of clusters in the form of sets of logical regularities is developed. Special attention is paid to detection of steady interrelations in data which are valid for considerable shares of the sample. The approach is based on usage of fast bit operations and positional method of data representation. New criterion of adjacency is proposed for high-level points of the representation, and it's used further in the process of assembling such points in maximal hyper-parallelepipeds corresponding to the best regularities. The method can be used as preliminary step in various tasks related to the search of essential logical regularities and substantial interpretation of data.

Authors:

Artem Myagkov, Elena Kozina, Vera Yashina, Igor Gurevich, Michael Ugrumov and Heinrich Niemann
Abstract: This work continues the development of mathematical tools and information technology elements for automated extraction and characterization of objects in striatum section images. The latter are used to construct a Parkinson disease model at a preclinical stage. Previously an automatic segmentation method for extracting of objects from striatum section image was developed. Now it is enhanced and extended to a form of an algorithmic scheme. It allows reducing brain section images to a form appropriate for recognition. Experimental applications of the developed technique have confirmed its high efficiency and suitability for automated processing and analysis of brain section images (a 200 times increase in productivity and a 10 times decrease in the amount of animals and expendables).

Title:

Cavity shape from parallel linear shading. A low-cost technique to collect data for an Image Mining oriented Geoprocessing System
Authors:

Renato Guadagnin, Vanessa Gonçalves da Silva, Edvar Rocha, Rinaldo Neves, Levy Santana and Jose de La Mata
Abstract: An Image Mining oriented Geoprocessing depends essentially on spatially defined information from images. So it is possible to support decision-making quite suitably in several areas, such as environment management, urban management and health care. When large-scale use of image capturing and interpretation devices becomes possible, it seems attractive to have low cost additional infrastructures. This paper discusses the extraction of geometric features of cavities, primarily motivated by the need for monitoring patients with wounds called pressure ulcers (PU). An image with linear shadows on the cavity of a model is generated in order to enable the measurement of its deformation caused by depth. This yields maximum depth and volume in an experimental model that are compared with measurements made previously in a conventional manner. Differences with conventional measurements are partially satisfactory and suggest further improvements in image capturing device and computational procedures.
