| 摘 要： | 传统插值算法放大后的图像产生细节模糊和边缘锯齿化,为此提出一种基于边缘检测的多方向模糊消除算法。采用双通道方式,边缘检测原图像,提取放大后的图像边缘信息,根据多方向边缘梯度变化,对边缘邻接像素点优化;多倍放大时采取小倍率递进方式实现。实验证明,算法模型简单易于实现,对提高图像质量取得了明显的效果。

| Abstract: | The image magnified by traditional interpolation algorithm has detail blurring and edge serrulation.A multi-direction image deblurring algorithm based on edge detection against this was proposed in the paper.This novel algorithm employed edge detection on image in double-channel way and picked up magnified image edge information to optimize the edge neighbouring pixels based on multi-direction gradient variety.The magnification of image was implemented in small rate progression.The experiment shown that the... |
