    Analiza sekwencji obrazów śladów tarcia ślizgowego kompozytów PTFE
    (Wydawnictwa AGH, 2006) Rudnicki, Zbigniew
    In the paper methods of analysis of microscopic image sequences of steel countersample disk are presented. These images were recorded during sliding of the samples of PTFE composites in pin-on-disk tribotester. The sequences show variations of thin layer of transferred composite material - so called »transfer film« - important in sliding friction process. The applied methods of noise evaluation and filtration and the method of binarization threshold calculation - based on image percentiles are described. Binary image features - showing transfer film changes - are defined and extracted. The function aproximation of experimental data are made. Conclusions and postulations of further research are formulated.
