Abstract:As one of the effective methods, image interpolation
is often used toestimatethe high-resolution (HR) images from
the low-resolution (LR) images, how to construct the fast image
interpolation algorithm becomes one of the problems that must
be solved in practical application. A bilateral 4degree (Bi4D)
interpolation is proposed to estimate the HR image of the LR
image. The interpolation region [i-2,i+2] is translated into the
region [-2,2][-2,2], and the pixel values of the translated region
are invariant corresponding to the interpolation region.
Similarly, the compensated pixel region [i,i+1][j,j+1] is
translated into the region [0,1][0,1]. Experimental results show
that the Bi4D methods achieve better performance than that of
the traditional interpolation-based and learning-based image
super-resolution methods.
Keywords:Bi4D, bicubic interpolation, low-resolution,
