摘要
通过将图像分为非边缘部分和边缘部分,得出了一种基于图像边缘信息的图像插值算法。根据边缘部分映射点邻域图像的复杂程度,自适应地调节插值权值的图像插值方法。应用该算法插值后的边界清晰、自然,忠实地反映了原始图像的面貌,与传统的插值算法相比,其边界处理效果好且易于实现,实验也验证了该方法的有效性。
An image interpolation algorithm based on image edge information can be elicited from dividing image into no-edge areas and edge areas. This method of image interpolation can adaptively adjust interpolation weight according to the complexity of image neighbourhood of mapping point in edge areas. The edge which applied this algorithm becomes more clear and natural, reflects the primitive features of image faithfully. Comparing with traditional interpolation algorithm, it can result in better effect of edge and can be realized easily. Experiments also prove the effectiveness of the method.
