摘要
在图像处理中,经常会碰到滤波器尺寸选择的问题,针对不同尺寸的目标需要选择与之对应尺寸的滤波器。在一幅图像中,可能存在多个不同尺寸的目标,或者在计算机自动目标检测系统中,不能确定目标的尺寸,这样就需要使用多种尺寸的滤波器进行滤波。如何将每种尺寸滤波器滤波后得到的最好结果融合到一起,是图像处理中的一种十分重要的关键技术。提出了一种基于改进的DS证据理论的融合方法,将多个不同尺寸的滤波结果进行融合。试验结果表明,该方法能够将图像中不同尺寸的目标很好的提取出来。
According to the targets with different sizes, different sizes of the filter modes need to be selected in image processing. Multiple targets with different sizes may be existed in an image, or the size of the target is not known at all in ATR system sometimes. Therefore, the filter with different sizes will be used to test in those situations. How to get the best results of the different filters together is a very important key technology in image processing. A method based on the improved DS evidence theory was presented. The experiment results indicate that the proposed method could well extract different sizes targets in an image.
