Computer Game Innovation
(Wydawnictwo Politechnika Łódzka, 2017) Wojciechowski, Adam; Napieralski, Piotr
The "Computer Game Innovations" series is an international forum designed to enable the exchange of knowledge and expertise in the field of video game development. Comprising both academic research and industrial needs, the series aims at advancing innovative industry-academia collaboration. The monograph provides a unique set of articles presenting original research conducted in the leading academic centres which specialise in video games education. The goal of the publication is, among others, to enhance networking opportunities for industry and university representatives seeking to form R&D partnerships. This publication covers the key focus areas specified in the GAMEINN sectoral programme supported by the National Centre for Research and Development.

Mobile vision based augmented reality navigation system
(Wydawnictwo Politechniki Łódzkiej, 2012) Wojciechowski, Adam
Augmented reality applications become more and more popular due to increasing computation speed of the mobile handsets and need of easy and intuitive navigation. Existing systems are implemented on the basis of GPS and compass where relative position and orientation of the handset is considered. Such hardware requirements decrease amount of compatible devices and limits system usage to outdoors where GPS signal is available. The paper presents a vision-based augmented reality navigation system implemented on the Android mobile phone. Image data of interest object and handset position are acquired by the users, however GPS position is not required for the system operation.

Robust Two-View Reconstruction Procedure for Geometrical Model Retrieving
(Wydawnictwo Politechniki Łódzkiej, 2018) Walczak, Jakub; Wojciechowski, Adam
In this paper we present the enhancement of the standard two-view reconstruction procedure. An ordinary approach assumes determination of points’ correspondences followed by projection matrix estimation, to finally refine results with bundle adjustment taking as a cost function reprojection error. Our contribution is realized in two manners: introducing an additional step of outliers rejection, changing cost function of bundle adjustment process to Relative Reprojection Error (єᴿ) and applying central difference as a method for Jacobian matrix approximation. Tests revealed gain in average єᴿ with lower variance, for confidence level of 0.95. Besides accuracy improvement, the suggested modifications supply the final result in the time virtually independent on initial object’s complexity and, in most cases, shorter than the standard approach.
