P Kennel, P Borianne, G Subsol - Computers and Electronics in Agriculture, 2015 - Elsevier
Abstract This paper describes an efficient method for delineating tree-rings and inter tree-
rings in wood slice images. The method is based on an active contour approach and a multi-
scale gradient map resulting from the Dual Tree Complex Wavelet Transform (DT-CWT). ...
[citation][year=2014]Combining grey relation analysis and entropy model for evaluating the operational performance: an empirical study
CC Sun - Quality & Quantity, 2014 - Springer
Abstract Decision-making on operational performance evaluation is a complex multi-
objective problem. Through the combination of grey relation analysis and information
entropy, the evaluation results are more objective and reasonable. This paper would ...
