Konferensbidrag (refereegranskat)abstract
- The paper manufacturing industry is currently exploring the possibility of measuring micro structural topography online in a paper manufacturing machine, which is intended to lead to a more precise measure of the paper quality reel to reel and a more efficient use of raw material. This paper presents a Matlab simulation model that can be used to configure such measurement readout systems, and includes a demonstration of the model in use. The model will also be used for research purposes in order to assist in gaining a better understanding of both the limitations and possibilities of such measurement systems. In this regard the angular shading of microstructures and Centre of Gravity (CoG) functions are included in the attributes that require further exploration.

Konferensbidrag (refereegranskat)abstract
- We present in this work an image component labeller- and feature extraction module that can operate in real-time. This labeller is suitable for smart cameras and Field Programmable Gate Arrays (FPGA). We show in our work how complex gray value features of image components can be calculated in parallel with label assignment without first resolving complex chains of merged labels. The labeller and a simple counter of number of image components are implemented on a Xilinx Virtex II Pro. We report device usage, maximum frequency and power dissipation.
