Wake Feature Images Extraction in Mathematics Morphology
Sun Jian-peng · Journal of Xi'an Technological University · 2012
Based on mathematical morphology,the principles and methods of extracting the image of ship wake vibration are introduced in this present paper to find a proper way of ship wake images(SWI) denoising.A clear denoising image of the wake edges can be achieved by applying the operation of mathematical morphology,including dilation,corrosion,opening and closing calculation.By trimming and refining the framework of the denoising image,a final image of ship wake vibration is achieved.SWI vibration with various noises and indistinct edges can be extracted by applying mathematical morphology to the research.Denoising SWI are received with clear hierarchy and sharpen edges through the processing of threshold of binary on SWI.
