DENIDIA project: a Marie Curie action to increase excellence in hardware and software development related to tomography applications
(Wydawnictwo Politechniki Łódzkiej, 2010) Babout, Laurent; Sankowski, Dominik
This paper summarizes the 4-year FP6 Marie Curie Transfer of Knowledge project, in terms of recruitment/secondment strategy, scientific organization and achievements related to tomography. Emphasis is placed on the interaction between different research areas that has been thought in order to increase the level of expertise of the Computer Engineering Department in the field of tomography, both concerning hardware and software applications.
Design of a new sensor to improve accuracy of ECT images
(Wydawnictwo Politechniki Łódzkiej, 2009) Liu, Z.; Babout, Laurent; Banasiak, Robert; Sankowski, Dominik
Electrical capacitance tomography (ECT) has been successfully applied in many industrial fields. However, the resolution of ECT still needs to be improved so that it can be used in a wider scope. As a first attempt to overcome this drawback, a new design is presented as a prototype system for improving the resolution based on rotation of the sensor. y keeping the number of electrodes constant, the image quality may be enhanced by making additional measurements at different angles.
Public engagement in science - education through the use of 3D technology applied in tomography
(Wydawnictwo Politechniki Łódzkiej, 2010) Tan, Kevin; Babout, Laurent; Janaszewski, Marcin
This paper summarizes one of the knowledge transfer scheme under DENIDIA Framework XI funded project at the Computer Engineering Department in the field of public engagement and 3D stereoscopic projection system. It will provide insight of how public engagement is important in terms of inspiring young students into science and engineering, particular computer scientist area. With the use exciting technology such as 3D stereoscopic projection system, it will make public engagement activiteis far more interesting than just ordinary 2D PowerPoint presentations.
Wavelet-based texture segmentation of titanium based alloy lamellar microstructure: application to images from optical microscope and X-ray microtomography
(Wydawnictwo Politechniki Łódzkiej, 2009) Babout, Laurent; Jopek, Łukasz; Janaszewski, Marcin; Preuss, Michael; Buffiere, Jean-Yves
A texture segmentation algorithm which combines grey level intensity from 2 images after discrete wavelet transform and variance has been applied on 2D images to segment lamellar colonies in (α+β) titanium alloy Ti6A14V. Images were acquired using both optical microscope and X-ray tomography. The results are satisfying for the former technique and encouraging for the latter one. Possible extension of the method to volumetric data is presented.
Zastosowanie algorytmów zamykania i wypełniania tuneli w komputerowej analizie materiałów na bazie tomograficznych obrazów 3D
(Wydawnictwo Politechniki Łódzkiej, 2010) Janaszewski, Marcin; Babout, Laurent; Postolski, Michał
Artykuł prezentuje szybkie, oryginalne algorytmy zamykania i wypełniania tuneli dla obiektów wolumetrycznych 3D oraz ich przykładowe zastosowania w badaniach materiałów z wykorzystaniem tomografii rentgenowskiej. Pierwsze zastosowanie dotyczy aproksymacji objętości wiązadeł mostowych w popękanej stali nierdzewnej. Następnie zaprezentowano badania nad strukturą poliuretanowych pian auksetycznych. Trzeci przykład dotyczy badań nad zgrzewaniem dwóch płyt będących stopami aluminium. Wszystkie zaprezentowane przypadki pokazują przydatność algorytmów bądź to na etapie wstępnego przetwarzania tomograficznego obrazu 3D lub na etapie ekstrakcji interesujących obiektów.
