Adaptive edge enhancement based on anisotropic image interpolation
Sheng-Hsien Hsieh, Ching-Han Chen, Yuan-Wei Tseng · 2010
This paper proposes an anisotropic probabilistic neural network image interpolation (APNNI2). The method used anisotropic Gaussian kernel to improve probabilistic neural network image interpolation (PNNI2) which caused blurring edge. The method is better for sharpness enhancement at edge region. We interpolate slanted-edge image to observe blurring and blocking effect. Finally, we report the performance of these newly proposed methods in other image interpolation method.
