Seamless Stitching of Images

Dr. Peter Hampton, a controls engineer here at Cellula Robotics Ltd., has recently co-authored a conference paper titled “Seamless Stitching of Images Based on a Haar Wavelet 2D Integration Method” with Ioana Sevcenco and Dr. Pan Agathoklis of the University of Victoria.

This paper is on mosaicking images in a manner that hides the borders of the sub-images.  The paper focuses on photographic images, but has potential for generating seamless maps from underwater surveys.  The process is resilient to misregistrations of adjacent images.  Further, the computation cost scales linearly with the number of pixels, allowing for much larger data sets to be processed than competing methods.

Cellula expands…

Cellula Robotics is pleased to announce the appointment of Peter Hampton, PhD as a new Control Systems Engineer.  Peter’s dissertation at UVic was related to the novel adaptive control of a large optical telescope; his addition to the team will enhance our capabilities in signal processing, control systems, electrical design & system modelling.

We have also leased some new office space a block away at 604 Columbia St in New Westminster.  The new “Cellula South” houses our electrical, software and controls team.  To contact this office, phone (604) 630-5577.
