摘要
立方卷积插值(Cubic算法)是一种常用的图像缩放方法。为了使喷码机喷印图像更加清晰可见,改善Cubic算法边缘模糊、分辨率低等不足,本文将形态学算子中的腐蚀运算与Cubic算法结合,以此进行了理论分析和实验验证。结果表明,此方法对提高图像边缘的清晰度和图像质量有明显效果。
Cubic convolution interpolation is a commonly used image scaling method,but Cubic algorithm has some disadvantages,such as fuzzy edge,low resolution and unclear the inkjet printing image.Combining theerosion of morphological operators,with Cubic convolution interpolation,the theoretical analysis and experimental verification were implemented.The results show that this method has obvious effect on enhancing the sharpness of the image edges and image quality.
