【摘要】 提出了一种基于切向细分方法的图像插值算法。使用该算法进行图像插值时无需建立中间连续模型,而且插值系数可为任意正实数。实验结果显示,该算法克服了经典插值后图像的边缘锯齿和模糊效应,应用该法插值所得图像不仅使修正优化后的图像边界清晰,而且拥有更高的信噪比。更多还原

【Abstract】 A new image interpolation method based on tangent-control subdivision was presented.This algorithm allows us to interpolate images from discrete to discrete with an arbitrary real positive scale.Comparative experiments with several traditional image interpolation algorithms indicate that our method preserves edges to which the human visual system is sensitive successfully.Moreover, corresponding PSNR(peak signal to noise ratio) results are also shown.更多还原
