摘要
根据李将云等人(2003)所提出的数字图像的离散放缩算法,分析其不足之处,并对简单的二值图像以及一般的灰度图像提出一套新的离散放大算法.该算法可使图像放大任意实数倍.应用该算法能使放大后的图像边界清晰,忠实地反映原始图像的面貌.实验证明,该方法也是一种有效的图像放大算法.
A discrete algorithm for image zooming is improved.Another one for binary image and grayscale image zooming in 3D is presented.The method can enlarge the image with arbitrary real positive scaling factors and can keep the edges as clear and natural as possible.Experimental results show that the proposed method can improve the quality of zoomed image effectively.
