Image Zooming Based on Oriented Laplacian Operator
Xiaochun Liu · Modern Electronics Technique · 2011
To overcome the shortcomings of conventional interpolation and partial differential equation(PDE) methods,an image zooming method with edge-enhancing function based on oriented Laplacian operator is introduced.Starting from the interpolated image,the proposed PDE equation is resolved iteratively,and the zoomed image is obtained until the process is terminated.Experiments demonstrate that the proposed zooming approach can achieve better results such as edge-preserving and details-preserving than traditional bilinear interpolation method and P-M equation.
