【摘要】 为了提高内膛全景图像对比度,本文基于Contourlet变换,提出一种新的内膛全景图像增强方法。该方法在图像空间域增强的基础上,通过对图像Contourlet变换系数的调整,进一步增强了内膛图像。实验结果表明,本文算法在增强内膛图像对比度的同时,减少了图像细节的丢失,改善了图像质量。更多还原

【Abstract】 In order to enhance the contrast of gun bore panoramic image,a new enhancement method for gun bore panoramic image based on Contourlet transform is proposed in this paper.The method enhances the bore image by revising the Contourlet transform coefficients of the image on the basis of the spatial image enhancement.Experimental results show that the proposed algorithm improves the bore image contrast and the image quality significantly,while reducing the loss of image detail.更多还原
