An Interpolation Algorithm By Using The Adative Pseudomedian Filter
PROCEEDINGS OF THE SECOND IEEE ASIA PACIFIC CONFERENCE ON ASICS(2000)
摘要
In this paper, we propose a digital image interpolation method that improves the reconstruction of the edge component by selectively transposing the sub windows of pseudomedian filter that shows relatively better performance than others. In order to compare the picture quality of the proposed method with that of the conventional;methods, computer simulation has been executed by checking PSNR, which is better than others from the point of view on the edge and local characteristics of the image. When we judge the images with our eyes, the simulation results showed that the proposed method is better than others in the point of view on the edge and local characteristics of the image.
