FPGA-Based Implementation of Real Time Optical Flow Algorithm and Its Applications for Digital Image Stabilization
PublicationAn efficient simplification procedure of the optical flow (OF) algorithm as well as its hardware implementation using the field programmable gate array (FPGA) technology is presented. The modified algorithm is based on block matching of subsets of successive frames, and exploits one-dimensional representation of subsets as well as the adaptive adjustments of their sizes. Also, an l1-norm-based correlation function requiring no...

A numerical model to simulate the motion of a lifesaving module during its launching from the ship’s stern ramp
PublicationThe article presents a numerical model of object motion in six degrees of freedom (DoF) which is intended to be used to simulate 3D motion of a lifesaving module during its launching from a ship using a stern ramp in rough sea. The model, of relatively high complexity, takes into account both the motion of the ship on water in changing sea conditions, and the relative motion of the ramp with respect to the ship. The motion of the...

Revitalized Mill Island in Bydgoszcz - the identity of the place created by the Brda River and its tributary named Młynowka
PublicationMill Island in Bydgoszcz, Poland is an example of downtown public space where a meander of the Młynówka creates the identity of the area.Before 2005, the only outstanding local feature was the fact that its south and west ends resembled the Venetian canals. The way the other parts of Mill Island were managed was inappropriate for a downtown.A comprehensive revitalization programme is returning Mill Island public space to residents,...
