Abstract :
The retargeting pyramid (RP) is a multiscale image pyramid using content-aware image resizing. In the previous implementation of the RP, a two-step interpolation is adopted to obtain the desired resolution. However, this interpolation leads to performance loss for image processing. In this paper, we improve the performance of the RP by replacing the two-step interpolation with a single interpolation using a matrix representation of the bilateral filter and Tikhonov regularization.
