Methods of data filtration and their effects on the resulting image of a log at the electronic sensing its dimensions

Popis výsledku v původním jazyce

The data taken at the electronic reception of logs are tasked with mistaken values and do not correspond to the real shape of a stem. The aim of the data filtration is to remove the incorrect data and replace them by the ones, closer to the real values.The goal of presented work was to analyse the effect of different filtration methods on original data and to recommend the methods, which results correspond to the real shape of the logs with their defects on a surface as close as possible. Methods of filtration are based on simple mathematical and statistical procedures, which are subsequently variously combined, because the simplest comparative methods did not fulfil the expectations. More than 50 methods were combined and analyzed. Approximately 15 of them were selected and tested. The methods were applied to data scanned on ca 150 logs randomly selected from thousands of files in the sawmill log yard. The filtration effects of different methods were visually assessed. The most appli
