Abstract
It is an essential fundamental to evaluate the ship wake image's quality quantitatively and effec-tively,and to achieve the extraction of ship wake's optical signal characteristics rapidly in today's ship op-tics-wake elimination technologies. The method regarding quality evaluation of ship wake images is stud-ied in this paper based on the contrast model. By analyzing the characteristics of the obvious contrast be-tween the wake area and the seawater background area in ship wake images,this paper uses the contrast parameter as an critical index for the wake image quality evaluation process as well as the characterization of ship wake's optical signal characteristical strength. Specifically,in order to evaluate the actual quality of ship wake images,the weighting factors on both wake areas and seawater background areas are intro-duced,and the basic contrast calculation model is improved. This model fully considers the human visual characteristics and combines the subjective and objective evaluation methods comprehensively. A corre-sponding experiment is also conducted,which particularly focuses the maritime feature extraction. The re-sults show that the contrast parameters do not only reflect the subjective visual perception of human eyes on the wake images' actual quality,but also better reflect the application essence of the wake image pro-cessing. In brief,the contrast parameters reliably and quantitatively describe the intensity's changing rules of the ship wake's optical signal characteristics.关键词
