An Improved Median Filtering Method and its Applications in Feature Extraction of GRIN Lens End Image
PROCEEDINGS OF THE 2016 INTERNATIONAL FORUM ON MECHANICAL, CONTROL AND AUTOMATION (IFMCA 2016)(2017)
Abstract
In this paper, animproved median filtering method for particular local grey level is presented andused to the image processing experiments of gradient-index (GRIN) lens end face. The principle and methodology of image processing for features extraction of defects in GRIN lens end are introduced, on the basis of the proposed median filtering, threshold segmentation, and morphological statistics of local featureinformation. In the method, the determination process of defects information is described abstractedly, including the pre-processing, classification and determination. Innovative experiment methods and promising results are presented in this paper.
