会议简介:The International Society for Condition Monitoring (ISCM) and the British Institute of Non-Destructive Testing (BINDT) are delighted to invite you to this global event. This congress is of major significance, being the first world event in its field. Ownership and overall control of the event rests with the ISCM and this premier event is being organised in the United Kingdom by BINDT in collaboration with almost all condition monitoring and NDT societies worldwide. This combination of efforts will create one of the largest events of its kind at a truly international level. The event will provide you with a unique opportunity to network with leading academics and industrialists from all over the world in the field of condition monitoring and related areas.

Title: An Adaptive Thresholding Segmentation Method of Ferrographic Image for Oil Condition Monitoring
Author: Bin Xu, Guangrui Wen, Zhifen Zhang*, Feng Chen
Abstract: Ferrographic image segmentation is of great significance in wear particles recognition and oil condition monitoring. In this paper, an adaptive thresholding segmentation (ATS) methodology was proposed to process ferrographic images for oil condition monitoring. Firstly, the preliminary conceptions of newton interpolation polynomial and difference quotient were briefly introduced, and the grayscale ferrogrphic image was converted into three-dimensional gradation histogram. Then, the slicing operation for three-dimensional gradation histogram was conducted, and the pixels number of each slice was used to plot the curve of slice grayscale-frequency. The two acceptable functions and two acceptable errors were generated from the curve of slice grayscale-frequency. Subsequently, the acceptable threshold can be selected adaptively based on the acceptable functions and errors. Segmentation performance of the ATS method was assessed and validated using a variety of ferrographic images. By comparing with three classical algorithms i.e. Riddle’s iterative thresholding method, Kapur’s maximum entropy method and Otsu method, the results showed that the proposed method possess better performance on both segmentation accuracy and noise resistance. The promising results suggest that the ATS algorithm can be considered as an effective alternative for ferrographic image segmentation.
